Anion-exchange behaviour of several elements in systems containing formic acid.
The anion-exchange characteristics of 27 elements toward the strongly basic anion-exchange resin Amberlite CG-400 in media containing aqueous formic acid and mixtures of formic acid with sodium formate, hydrochloric acid, sodium nitrite, acetone and methanol have been investigated. Possible separations are described and discussed. The quantitative separations achieved are Sr-La, Zn-Cd-Hg, and Ni-Fe.
