Abstract :

Heavy metal pollution is propagating throughout the world with the enlargement of industrial activities. The elimination of heavy metal ions from industrial wastewaters has drawn much attention 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 multi cyanocyclopropane functionalities in the pendant group were prepared by reacting benzoyl peroxide with p-(2,2,3, 3-tetracyanocyclopropyl) phenylacrylate (TCP) monomer. (TCP) monomer was synthesized by reacting cyanogen bromide and malononitrile with p-acryloyloxybenzaldehyde at 0 °C in a short time. The synthesized PTCP momopolymer were examined in heavy metal ions adsorption such as Ni (II), Cu (II), Cr (III) and Zn (II) under competitive and non-competitive conditions in aqueous solutions at different pH. The high adsorption rate (<65 min) was seen. The synthesized polymer and its metal chelates were investigated by thermogravimetric analysis (TGA),Fourier-transform infrared spectroscopy (FT-IR), atomic absorption techniques (AAS), UV-vis spectroscopy and scanning electron microscopy (SEM).
