Copper is produced
as a byproduct of many industrial processes.
Dyna-AquaTM 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.
Dyna-AquaTM
Copper is an ideal medium for copper removal from
wastewater. 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.
