English Abstract

N,N-diallyl-N-sulfopropylammoniopropylphosphonic acid and a cross-linker using tertbutyl hydroperoxide (TBHP) initiator to give cross-linked polyzwitterion (CPZ). The cross-linked polyzwitterion/dianion (CPZDA) was accessed by the treatment of CPZ with NaOH. New hydrophobic cross-linked dianionic Polyelectrolytes (HCDAP) was synthesised by cyclopolymerization involving N, N-diallyl-N- aminomethylphosphonic acid and a crosslinker using 2,2-Azo-bis-isobutyronitrile (AIBN) initiator to give hydrophobic cross-linked polyzwitterionic acid (HCPZA). Hydrophobic cross-linked dianionic Polyelectrolyte (HCDAP) was accessed by the treatment of HCPZA with NaOH. The adsorption efficiency of the resins were evaluated for Ni2+, Co2+, Cd2+, and Cr3+ from water. Influence of temperature, contact time, pollutant concentrations, sorbent dose and pH were investigated for the optimum conditions as well as thermodynamic and adsorption kinetics. The experimental data fitted Langmuir, Freundlich and Temkin isotherms. The adsorption activity of the polymers was tested under optimum treatment conditions for real wastewater
