Effective Removal of Heavy Metal Ions Zn^2+, Ni2+, Cu^2+, Cr^3+ from Aqueous Solution by Synthetic Superabsorbent Polymer

Heavy metal pollution is propagating throughout the world with the enlargement of industrialactivities. the elimination of heavy metal ions from industrial wastewaters has drawn muchattention because of the hazardous effects of the heavy metal ions on different organisms.according to these facts, poly (2, 2, 3, 3- tetracyanocyclopropyl) phenyl acrylate (ptcp) with multicyanocyclopropane functionalities in the pendant group were prepared by reacting benzoyl peroxidewith p-(2,2,3, 3-tetracyanocyclopropyl) phenylacrylate (tcp) monomer. (tcp) monomer wassynthesized by reacting cyanogen bromide and malononitrile with p-acryloyloxybenzaldehyde at 0°c in a short time. the synthesized ptcp homopolymer were examined in heavy metal ionsadsorption such as ni (ii), cu (ii), cr (iii) and zn (ii) under competitive and non-competitiveconditions in aqueous solutions at different ph. the high adsorption rate (<65 min) was seen. thesynthesized polymer and its metal chelates were investigated by thermogravimetric analysis (tga),fourier-transform infrared spectroscopy (ft-ir), atomic absorption techniques (aas), uv-visspectroscopy and scanning electron microscopy (sem).
