SEPARATION OF CADMIUM BY CHELATING POLIMERIC SORBENTS AND APPLYING PRECONCENTRATION
Journal Title: Azerbaijan Chemical Journal - Year 2019, Vol 0, Issue 3
Abstract
Copolymer of maleic anhydride with styrene is modified and two new chelating sorbents are synthesized. These sorbents contains fragments of m-phenilendiamine (S1) and diaminobenzidine (S2). The sorption conditions of cadmium with these sorbents were investigated for the first time (pH=5, =6•10-2 mol/l, Vliquid=20 ml, msorbent=0.05 g, СЕ=487 mg/g (for S1) and СЕ=509 mg/g (for S2). Sorption was studied in static and dynamic modes. The results of the study showed that the maximum sorption of sorbents S1 and S2 is observed at pH 5. The effect of metal concentration on sorption was also studied. The developed methodology has been applied to isolate cadmium(II) from the water of the river Agstafa and the river Jogaz of the Kazakh region of the Azerbaijan Republic
