| Abstract: | The extraction of PAN chelates of the group IB, IIB and IIIA–VA elements from aqueous solutions of pH 1–10 into chloroform
has been studied radiochemically. Re-extraction studies have been made to strip the metal ions from the organic phase into
aqueous solutions of KCN, HClO4 and buffer solutions. The effects of certain masking agents on the extraction of these elements have also been studied. The
extraction curves indicate the possibilities of devising group chemical separation procedures for use in activation analysis. |
