Chelating resins for recovery of trace metal ions.

Masahide Hirai

Abstract

Recently, new type chelating resins which are highly selective for certain metal ions have been synthesized and these selective separation character of metal ions has been investigated. Also, metal pre-adsorbed ion exchange resins or chelating resins have been used for removal of some anions, such as As, F.This review presents recent studies on the recovery of precious metals such as U, Ga, In, Ge, V, Mo, Au, Pt, and Pd, on the removal of harmful metal ions such as Sb, Bi, Fe, Cr, Ca, Mg and on the removal of certain anions such as As, and F.
