On the concentration and separation of the trace elements: Fe, Cu, Zn, Mn, Pb, Mo and Co : Ion exchange methods

Abstract

Cation-exchange materials and selective elution with acetone-hydrochloric acid mixtures are used to concentrate the constituents of biological ashes and to separate them into the groups: MoO4-2, SO4-2, PO4-3, Fe+3, Zn+2, Pb+2, Cu+2, Co+2, Mn+2; Na+, K+, Ca+2, Mg+2.
