Since the industrial revolution a huge amount of pollutants
emitted annually into the water most of which is
occupied by toxic metals. These metals widely distributed
in the environment and of accumulation of a
threat to human health. It is known, that cadmium and
zinc at high concentrations have a negative impact on
nature. In modern wastewater treatment technology we
widely use polymeric sorbents with chelating properties.
The use of polymeric chelating sorbents (PCS)
usage allows separating individual or group trace elements
from large volumes of solutions of complex
composition, lowering the limit of detection, eliminating
or reducing significantly the impact of macrocomponents
which increases the cleaning efficiency.
The article presents the results of a study of conditions
of interaction of zinc (II) ions and cadmium (II) with
PCT - polystyrene-azo-o-phenol-azo-rhodanine. We
found the optimal values of the conditions for zinc (II)
ions and cadmium (II) sorption. We investigated the
effect of interfering of the macro- and micro- water
components with the sorption of the ions studied.
Maximum desorption of metal ions is achieved by
washing the concentrate with 10 ml of 2M hydrochloric
acid. The data indicate availability of the investigated
sorbent for concentration and separation of zinc
(II) ions and cadmium (II)
