✦ Synopsis
On mixing of aqueous solutions of polyethylene glycol2000 and Triton X-100 (polyoxyethylene alkylphenol) and addition of ammonium sulphate, a polymeric solid phase and an aqueous phase are formed. Suitable phase separation conditions were studied in addition to the distribution of the Arsenaxo III complexes of U(VI), S&II), BifIII), Z&V), FeUII) and PbfII) between the two phases. The separation of zr(IV) from Fe(II1) and the determination of the former was achieved by properly adjusting the acidity of the solution.
