| Abstract: | In milkiness liquid film system of tri-butyl-phosphate, N,N-dioctylacetamide, sulfonated kerosene , thiourea and Na2SO3 solution, the transfer behavior of Tl3 was investigated. On selective condition, transfer ratio of Tl3 was over 99.4%. On the condition, Cu2 ,Pb2 ,Zn2 ,Co2 ,Ni2 ,Cd2 ,Ca2 ,Mg2 ,Fe3 ,Al3 ,Mn2 ,Au3 etc couldn't be transferred, but Tl3 could be separated and preconcentrated from these ions. The method has been applied the determination of trace Thallium in industrial seawage with satisfactory results. |
