DAI Wrote
the Book on Alumina - Producing the Highest Quality
of Alumina in the Industry
The DAI team wrote the book when
it comes to activated alumina. Literally, not
figuratively. For over 40 years innovations by the
DAI team have played a major role in the exponential
growth of the use of alumina for chromatography and
other separation technologies.
Standardized Alumina has become synonymous with
Dynamic Adsorbents. Never before has an adsorbent
been more precisely standardized and introduced such
a high degree of reproducibility when used in
laboratory and plant operations. This leadership
lent its impulses to all other Dynamic Adsorbents'
products such as silica gels and products for thin
layer chromatography, liquid chromatography and the
preparative link between TLC and column
chromatography: dry column chromatography.
DAI’s alumina for chromatography
has contributed to the continued growing use of this
material in a diverse number of applications.
Indeed, the major reason for this growth has been
our contribution to the standardization of the
manufacturing process. This has resulted in
standardized grades of alumina that are very well
controlled and defined.
Dynamic Adsorbents’ aluminas are
manufactured and quality assured providing world
class laboratory and pilot process chromatographic
materials. We carefully control the manufacturing
process from raw material to finished product
including physical characteristics of pore size,
surface area, particle size and surface chemistry to
ensure reproducible optimized chromatographic
behavior, making us unique in the industry.
Advantages of DAI alumina include:
- The highest
quality of alumina in the industry according to
independent lab tests (Read More)
- Unique forms of alumina that are superior to
anything else in the industry
- Control of the manufacturing process from raw
material to finished product insuring the highest
quality and standardization
- Specialty aluminas targeted towards particular
applications
- Customization to unique or specific needs of
companies
- Purchasing options that
include bulk purchasing or prepackaged

chromatography and/or TLC with the lowest everyday
price to many research institutions, pharmaceutical
companies, and organic synthesis labs. DAI's bulk
silica gels are used for low pressure and high
pressure columns. DAI's silicas have virtually no
traces of metals contained within, and the particle
distribution is kept extremely tight for
reproducible results. All silicas can come with MSDS
sheets, as well as Certifcates of Analysis if
requested. Dynamic Adsorbents, Inc. silica gels are
carefully manufactured and quality assured to
provide the ideal laboratory and pilot process
chromatographic material.
Reproducible performance is
delivered regardless of the technique used,
especially when transferring from one technique to
another. Silica gel is an ideal media for column
chromatography for several different reasons. Silica
gel has a very strong affinity for water, which
gives it an adsorption capacity of over 40% of its
own weight at 100% relative humidity. It is
compatible with most materials except strong alkalis
and hydrofluoric acid. Adsorbent particle size
affects how the solvent flows through the column.
Smaller particles (higher mesh values) are used for
flash chromatography, larger particles (lower mesh
values) are used for gravity chromatography.
Advantages of DAI silica over
that of competitors' include:
- The highest quality of
silica
in the industry according to independent lab tests

The Dyna-Aqua™ line
of specialized alumina oxides represents an
extraordinary breakthrough in the removal of toxic
metals and other toxic materials from water.
The Dyna-Aqua™ line of
specialized alumina provides a much simpler,
reproducible and cost effective solution using
specially modified alumina oxides which are able to
bind toxic metals and other industrial chemicals and
then lead to their easy disposal. Compared to other
existing technologies, there is no more efficient
and cost effective solution for the isolation and
removal of toxic compounds from our water supply.
DAI-Aqua™ specialty alumina oxides are manufactured
to rigorous standards and are customized for each
toxic water borne compound.
Environmental
cleanup has become a national priority. New cost
effective, low energy demanding and simple solutions
are required to successfully address this important
and pressing issue. Wastewater purification is
essential for not only environmental cleanup, but to
reduce the risk of exposure to carcinogens causing
excessive malignancy disease and death. There is no
such thing as “one solution addressing all needs.”
Specialized materials are critical for the
purification of toxic materials such as arsenic,
copper, uranium, selenium, lead and synthesized
materials such as polychlorinated biphenyls.
Multiple solutions
have been offered to address this pressing
environmental need. However a much simpler,
reproducible and cost effective solution lies in the
design and manufacture of specially modified alumina
oxides which are able to bind toxic metals and other
industrial chemicals and then lead to their easy
disposal. There is no more efficient and cost
effective solution for the isolation and removal of
toxic compounds from our water supply.
Dyna-Aqua™ specialty
alumina oxides are manufactured to rigorous

Dyna-Aqua™ Copper
Dyna-Aqua
™Copper is a
specially designed activated alumina oxide which is
recommended for the isolation and removal of copper
found in waste water in either a suspension or
solution form.
Copper is produced as
a byproduct of many industrial processes. Dyna-Aqua Copper is
designed especially for the recovery of copper from
spent solutions produced in printed circuit (wiring)
board manufacture and electroplating
It is currently
thought that one difficulty in the commercial
removal of copper from solution is that the metal
forms into complexes such as with benzotriazoles or
other triazoles. Activated alumina oxides are able
to address this issue and remove the complex by the
process of adsorption with high efficiency.
Adsorption is defined as the interphase transfer of
material from a homogeneous or heterogeneous fluid
matrix onto a solid surface.
Unlike organic
pollutants, the major of which are susceptible to
biological degradation, copper is not biodegradable
into a nontoxic end product. It must be reduced to
acceptable levels prior to being discharged into the
environment in order for manufacturers to be in
compliance with the Federal Clean Water Act, with
the federal regulatory limit for discharged copper
in suspension or solution being 1.3 mg/Liter.
Furthermore
competitive commercially available technologies such
as ion exchange, chemical precipitation,
ultafiltration and electrochemical deposition are
costly – chelating and ion exchange resins are
expensive.
The ideal solution to
clean up of industrial wastewater would be to find
an adsorbent which could avoid the need for
co-precipitation and pH adjustment. The sorption of
copper is highly pH dependent with an increase in
the amount of adsorption with increasing pH.
The amphoteric property of specialty activated alumina
is able to do away without the need for the
coprecipitant, and the compound is able to enhance
copper removal as the pH of the solution increases.

Dyna-Aqua™ Lead
Dyna-Aqua™ Lead is a
custom designed large particle activated alumina
based metal oxide for the removal of lead from
industrial wastewater with an effective size of
greater than 200 microns. It is specifically
designed, modified and chemically treated in order
to enhance the removal of dissolved lead from a
water stream. It is ideal for point of use
applications and more cost efficient and less energy
intensive than reverse osmosis, the only other
commercially available point of use technology. Dyna-Aqua
Lead offers a cost efficient, simple and reliable
solution for municipal, industrial and home use
needs.
Dyna-Aqua™ Lead provides benefits superior to either chemical
precipitation or ion exchange, commercial techniques
which are costly due to the high cost of required
chemicals.
Lead transported
through the water system comes from:
- Lead piping
- Lead solder
- Stabilizers used in the extrusion of PVC piping
- Brass fittings which are composed of copper, zinc
and lead corroding when chloramines are used to
disinfect water, leading to the production of
ammonia
Lead levels are
monitored by the Environmental Protection Agency and
cumulative exposure can lead to irreversible damage
to the gastrointestinal, hematologic and nervous
systems and may cause death.
Water
characteristics promoting the corrosion of water
include low pH, low total dissolved solids, high
water temperature and high concentrations of
dissolved gases such as oxygen or carbon dioxide.
Adsorption results
show pH dependency with a Freundlich isotherm fit.
Activated alumina possesses both Lewis and Bronsted
acidic and basic sites. While being amphoteric
alumina works best for lead removal when the pH of
the aqueous stream is in the pH range of 5.5 to 6.0.

Fluoride
This wide pore
specialized activated alumina is designed to address
municipal and industrial waste water needs. High
concentrations of natural fluorides are of
significance in some regions of the United States
including New Mexico, West Texas, Colorado, Indiana
and Illinois. Additionally fluorides are a waste
product in association with glass manufacturing,
electroplating, and the production of steel and
aluminum, pesticides, fertilizer and semiconductor
manufacturing. The maximum contaminant level for
fluoride established by the Environmental Protection
Agency is established at 4 parts per million, with a
secondary standard set at 2 parts per million.
Removal of fluoride from municipal and industrial
waste water may be obtained by precipitation, as
well as membrane and adsorption processes. The best
way, bar none, to reduce the concentration of
fluoride to 1 part per million or less is through
adsorption onto specially designed wide pore size
activated alumina.

The enforcement
role of the Food and Drug Administration will
strengthen during the years of the Obama
administration, assuring the public of a safer food
and drug supply. Excitement is generating in the
world of science that after the legacy of the Bush
years the pharmaceutical and life science industries
may once again be looked upon as economic growth
engines spurring the creation of thousands of well
paying jobs.
Tougher regulatory
controls will place heightened demands upon the
pharmaceutical and nutriceutical industries to
carefully quality control raw materials,
manufacturing processes and finished goods. High
quality DAI alumina and silica are currently
incorporated into current Good Manufacturing
Practices (cGMPs) for the production of ethical
pharmaceutical compounds originating as natural
plant alkyloids and being used in the treatment of
malignancies.
A new product line
has been developed specifically to address the needs
of the ethical pharmaceutical and nutriceutical
industries. For those drugs which are manufactured
using bacterium as “cellular factories” a
significant problem has been the removal of
endotoxins. These are lipopolysaccharides located on
the outer lay of the cell membranes of gram negative
bacteria and they make up the majority of the
pyrogens which must be removed from pharmaceutical
products, biologicals for injection and media used
for cell culture. Small amounts of endotoxin when
injected into patients may cause systemic
inflammatory reactions running the spectrum from
tissue injury to endotoxin shock to death. Gram
negative bacteria are able to release small amounts
of other materials capable of causing endotoxin
reactions such as exotoxins, peptidoglycans and
muramyl peptides. Specially designed alumina with
surface modified chemical moieties has proven to
provide a superior tool for the purification of
endotoxins due to its amphoteric property.
DynaPharma™
Pyrogen
Formerly named
Alumina P, DynaPharma™ Pyrogen is a
specially designed superior alumina for the removal of endotoxins and
pyrogens from bacterial cell culture systems.
The isolation of
therapeutic molecules from bacterial cell growth is
hampered by the need to remove endotoxins and
pyrogens. Many different commercial techniques are
in place in an attempt to remove these endotoxins,
which are lipopolysaccharide components of bacterial
cell walls.
DynaPharma™, using
either column chromatography or batch processing
methods has, proven to be a superior tool for the
isolation and removal of pyrogens. The surface of
activated alumina may be chemically modified to help
enhance pyrogen removal. Furthermore, the amphoteric
property of activated alumina offers unique
purification advantages allowing Alumina P to be
used either as a single step or as part of a two
step purification process for the isolation and
removal of endotoxins.
