Abstract |
Insoluble solid porous ethyl-2-iminobenzoate immobilized polysiloxane ligand system of the general formula P–(CH2)3–NH(C6H4)COOC2H5, (where P represents [Si–O]n siloxane network) has been prepared by the reaction of 3-iodopolysiloxane P–(CH2)3–I with ethyl-2-aminobenzoate. The modified polysiloxane derivatives; imino(N-2-aminoethyl)benzamide P–(CH2)3–NH(C6H4)CONH(CH2)2NH2, and imino(N-diethylenediamine)benzamide P–(CH2)3–NH(C6H4)CONH(CH2)2NH(CH2)2NH2 ligand systems were prepared by the reaction of ethyl-2-iminobenzoate ligand system with ethylenediamine and diethylenetriamine, respectively. The new modified polysiloxane ligand systems exhibit high potential for the uptake of the metal ions (Mn2+, Fe3+, Co2+, Ni2+, Cu2+ and Zn2+) with an efficiency of 92–98% after recovery from its primary metal complexes. These immobilized-polysiloxane ligand systems … |
