SELECTIVE SEPARATION OF IRON (III) FROM IMMOBILIZATION OF CATION EXCHANGER RESIN WITH TRIOCTYPHOSPHINE OXIDE SORBENT.

Reversed – phase extraction chromatography (RPEC) is an extremely versatile technique and has been applied successfully to the separation of various metals from organic compounds. In RPEC trioctylphosphine oxide (TOPO) has been extensively used for the extraction chromatographic separation of many metal ions. This paper describes systematic investigation of the extraction chromatographic separation of Iron on a Cation exchanger resin column with triotylphosphine oxide as the stationary phase. Methods are presented for the separation of iron from a large number of elements in multi- component mixtures. The method has been extended to the determination of Iron in real samples.
