Abstract: As a supplement to previous work this paper deals with the extraction of Fe(Ⅱ)fromnitrate solution with P538 at 30℃in various diluents: toluene, benzene, hexane, cyclohe-xane, kerosene, methylene chloride and carbon tetrachloride. The relationship between the distribution ratio D and solubility parameter δof diluentwas found as: lgD=-0.653+0.294δ-0.026δ2 at hi gher loading lgD=1.741-0.250δ +0.0083δ2.

Key words: extraction, phosphate, iron(Ⅲ)
