TitlePREPARATION OF IMMOBILIZED-POLYSILOXANE IMINO(2-AMINOETHYLACETAMIDE) AND ITS APPLICATION
Untitled
Abstract

porous solid polysiloxane ligand system of the general formula P-(CH2)3-NH-CH2COONHCH2CH2NH2, (where P represents [Si-O]n siloxane network) has been prepared by modification of the immobilized 3- aminopropylpolysiloxane, P-(CH2)3NH2, with ethyl chloroacetate followed by ethylenediamine. The new modified polysiloxane system exhibits good potential for uptake of metal ions (Co2+, Cu2+, Zn2+ and Pb2+). This ligand system gives more stable complexes with metal ions than its parent 3- aminopropylpolysiloxane precursor. Thermogravimetric analyses of this ligand system and its copper complex show high stability at relatively high temperature.
