TitleSynthesis of new polysiloxane-immobilized ligand system di (amidomethyl) aminetetraacetic acid
Untitled
Abstract

A new chelating porous polysiloxane-immobilized tetraacetic acid ligand system has been prepared. This material was made by chemical modification of the iminodiacetic acid polysiloxane with thionyl chloride and diethyliminodiacetate, respectively. The polysiloxane functionalized with di(amidomethyl)aminetetraacetic acid of the general formula P-(CH 2 ) 3 N(CH 2 C(O)N) 2 (CH 2 COOH) 4 [where P represents the polysiloxane backbones (Si‒O‒Si) n ] was characterized by Thermogravimetric Analysis (TGA) and FTIR spectra. The FTIR results proved that tetraacetic acid groups are successfully grafted onto the polysiloxane surface. This ligand system exhibits high potential for extraction of divalent metal ions (Co+2, Ni+2, Cu+2, and Zn+2) from aqueous solution.
