Removal of As(V) from aqueous solution using glycidyl methacrylate resin immobilized with Cu(II)-tetraethylenepentamine complex

Khalid Z. Elwakeel

Glycidyl methacrylate/ methelenebisacrylimide resin with tetraethelenepentamine ligand was prepared, investigated, and loaded with Cu(II). The adsorption characteristics of the obtained resin towards As(V) (asHAsO₄) at different experimental conditions were established by means of batch and column methods. The mechanism of interaction between As(V) and resin's active sites was discussed. The selectivity of the studied resin towards AsV) in the presence of other anions (Cl^-,NO₃^-,SO₄^2- and CO₃^2-) was evaluated. The kinetics and thermodynamic behaviour of the adsorption reaction were also defined. Regeneration and durability of the loaded resin towards the successive resin were also clarified.
