Abstract
ABSTRACT Chemically stable magneso-silicate (MgSi), polyacrylamide acrylonitrile P(AM-AN), and polyacrylamide acrylonitrile magneso-silicate [P(AM-AN)-MgSi] comparing with other ion exchangers ware synthesized at different radiation doses. The capacities of these composite materials for Ni 2+ , Cd 2+ , Co 2+ , Pb 2+ , Zn 2+ , and Cu 2+ were studied and the data revealed that the capacity of MgSi is higher that obtained P(AM-AN) by 0.6 value, and lower for [P(AM-AN)-MgSi] by 1.32 value. Distribution coefficients in HNO 3 show separation potentiality of prepared composites for studied cations and Cd 2+ have higher separation factor to MgSi and P(AM-AN), while Pb 2+ has higher separation factor to [P(AM-AN)-MgSi].
