As a supplement to previous work this paper deals with the extraction of Fe(Ⅱ) from nitrate 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 δ of diluent was found as:lgD=-0.653+0.294δ-0.026δ2 at hi gher loading lgD=1.741-0.250δ+0.0083δ2
