Preparation and Characterization of Polystyrene-Sulfonyl-Thiosemicarbazide Chelating Compound for Treatment of Wastewater Containing Heavy Metal Ions

This work studies the preparation of polystyrene-sulfonyl-thiosemicarbazide (PSS-TSC). Thio-polymer was characterized by IR, NMR, and elemental analysis. PSS-TSC was used fordetermination of metal capacity of Mn (II), Ni (II), Cu (II), Cd (II), metals ions. Hg (II) and Pb (II) in wastewater. Also the effect of pH (1-7) and shaking times (5 10 min) on the metal capacity were studied. Itwas found that the metal capacity values by PSS-TSC phase at pH 7 follow the following order Hg (II) greater than Pb (II) greater than Cu (II) greater than Ni (II) greater than Cd (II) greater than Mn (II). The efficiency of metal ions extraction by PSS-TSC phase was studied by the distribution coefficient and separation factor of different metal ions.
