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.

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.

DynaPharma™ Product Line

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 nutraceutical 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 alkaloids 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 nutraceutical 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.
