TitleExtraction of Co, Ni, Cu, Zn and Cd ions using 2-aminophenylaminopropylpolysiloxane
Untitled
Abstract

Insoluble porous solid functionalized ligand system bearing 2-aminophenylaminopropyl chelating ligand of the general formula P–(CH2)3NH–(C6H4)–NH2 was prepared via the sol–gel process, where P represents [Si–O] n polysiloxane network. First, the 2-aminophenylaminopropylsilane agent was prepared by substitution reaction between 3-chloropropyltrimethoxysilane and 1,2-phenylenediamine, followed by hydrolytic polycondensation between 2-aminophenylaminopropylsilane agent and tetraethylorthosilicate(TEOS). The immobilized 2-aminophenylaminopropylpolysiloxane P–(CH2)3NH–(C6H4)–NH2(P–AphA) was characterized by 13C NMR, XPS, and FTIR. The results showed that 1,2-phenylenediamine groups were introduced onto polysiloxane network. The functionalized ligand system exhibits 90–100% metal uptake capacity for all metal ions except Cd2+. The elemental …
