Template Synthesis of Immobilized polysiloxane Diamine-Thiol tetraacetic acid Bi-Ligand system and its application for determination of metal ions
Résumé
A bi-functionalized porous solid diamine-thiol tetraacetic acid P‒(NN-SH)-TAA immobilized polysiloxane ligand system (where P represents [Si‒O]n polysiloxane network, (NN-SH) represents both diamine and thiol groups, and TAA represents tetracetic acid group) has been prepared by modification of a post-polysiloxane bi-functional diamine-thiol ligand system P-(NN-SH) with ethylchloroacetate. The immobilized bi-ligand system was characterized by 13C‒NMR and Fourier transform-Infrared spectra. The bi-ligand system was used
