Equilibrium and kinetic sorption of some heavy metals from aqueous waste solutions using p (AAc-HEMA)‎

الملخص EN

Removal of heavy metals from aqueous waste solution using poly acrylic acid / 2-hydroxyethyle methacrylate ( p-AAc / HEMA) was investigated.

Experiments were carried out as function of contact time, initial concentration , pH, partipcle size and temperature .

Adsorption data were modeled using the pseudo-first-order, pseudo-second-order and intra-particle diffusion kinetics equations.

It was shown that pseudo-second-order kinetic equation could best describe the adsorption kinetics.

The results indicated that poly acrylic acid / 2-hydroxyethyle methacrylate ( p-AAc / HEMA) is suitable as adsorbent material for adsorption of Sr2+, Co2+, Cd2+, Zn2+, Nd3+ and Eu 3+ radio active nuclei from aqueous solutions.
