STUDY OF SORPTION OF LEAD (II) IONS BY ANIONITE OBTAINED ON THE BASIS OF ANILINE, EPICHLOROHYDRIN AND POLYETHILENPOLYAMINE

Abstract

Polyfunctional anionit based on aniline, epichlorohydrin, and polyamines were synthesized. The composition and structure of the anion exchanger were studied by IR spectroscopy and elemental analysis. Lead sorption was studied by classical polarography. Dependences on the sorption of lead (II) ions on the solution acidity, concentration of metal ions, and duration the contact of resins with solution Pb(NO3)2 were determined. This anionite exhibits high capacity in sorption of lead ions. The developed sorbents with increased sorption ability can successfully solve problems of removing lead (II) ions from process effluents in nonferrous metallurgy.
