THE SOLVENT EXTRACTION OF IRON WITH TRI-N-OCTYLPHOSPHINE OXIDE
The extraction of Fe fromacidic solutions with tri-noctylphosphine oxide (TOPO) was investigated. Iron is extracted only when the Fe is in the trivalent oxidation state and sufficient chloride ion is present in solution. Quantitative extraction was observed when the solution was at least 4 M or 1 M HCl--3 M NaCl. The loading capacity of 0.5 millimole of TOPO is approximately 16 mg of Fe from 7 M HCl. Quantititive extraction of 12 mg of Fe from 7 M HCl is possible in a single equilibration. Under these conditions extraction is quantitative at phase ratios as large as 20 to 1. The extracted species are probably FeCl/sub 3/ and HFeCl/sub 4/. (auth)
