Abstract
In this paper we report the results regarding the synthesis of two polyphosphazenes derivatives, from phosphazene having as side groups: o-tolylbiguanide and 4,4 - diamino 2,2 - stilbene disulfonate acid. These new polymers were characterised by NMR, FT-IR. In interaction with d metals they form coordinative species and on this base they can be used for removal of d metal ions (Cu2+, Cr3+; Mn2+, Fe2+; Co2+, Ni2+) from wastewaters.
