Abstract

The batch removal of copper (II) from aqueous solution under different experimental conditions using silicon-organic sorbent poly[N,N’-bis(3-silseskquioxanilpropyl)thiocarbamide] (PSTM-3T) was investigated in this study. This sorbent was produced from the hydrolytic poly-condensation reaction. The removal was favoured at pH = 5 for PSTM-3T. The effects of concentration and temperature have been reported. PSTM-3T was found to efficiently remove Cu(II) from solution. The batch sorption kinetics have been tested for a first-order reaction. The rate constants of adsorption have been calculated. The thermodynamic parameters (ΔG0, Kc) obtained to indicate the endothermic nature of Cu(II) adsorption on PSTM-3T.
