| Abstract: | The extraction behavior of Fe(Ⅲ), Cu(Ⅱ), Co(Ⅱ), Mn(Ⅱ), Pb(Ⅱ), Ni(Ⅱ) and Hg (Ⅱ) by microemulsion Triton X-100 (α- ( 4- ( 1,1,3,3-tetramethy (butyl) phenyl )-w-hydroxy) poly (oxy-l,2-ethanediyl) in the presence of (NH4)2SO4 and complexing agents were investigated. The results indicated that the complexes of Fe (Ⅲ) with aluminon were almost completely extracted in HAc-NaAc buffered microemulsion while Cu(Ⅱ), Co(Ⅱ), Cd(Ⅱ), Mn(Ⅱ) and Hg(Ⅱ) were not.Quantitative separation of Fe(Ⅲ), Co(Ⅱ) and Mn(Ⅱ) were realized. The extraction mechanism by O/W microemulsion has been discussed. |
