| Abstract: | Two organic–inorganic type composite materials were prepared via the incorporation of organic conducting polymers into the inorganic precipitates of multivalent metal acid salts to explore their analytical and environmental applications. Vital uses of these materials for the analyses of water pollution were demonstrated by the quantitative separation of Cd2+ and Hg2+ from some synthetic and real samples onto their columns. Separation and determination of Zn2+ and Fe2+ in the pharmaceutical preparations were also performed. The adsorption behavior of dichlorvos (insecticide) on the surface of polyaniline Sn(IV) tungstoarsenate was studied which indicating its usefulness in the decrease of environmental pollution load. |
