摘要
研究了从硫酸介质中用二－（２－乙基己基卜磷酸（Ｐ２０４）与Ｃ５－７氧肟酸协同革取Ｇｅ４＋的机理，经斜率法确定了其革取Ｇｅ４＋的机理和萃合物的组成．基于红外光谱的研究，探讨了协革配合物的结构．
The characteristics of extraction of Ge4+ from stlfuric acid medium with themixture of P204 and C5-7 oximine acid in kerosene airs investigated. The experimental re- sults show that there is obvious synergistic effect in the Ge4+/ H2SO4-H2O /P204-C 5 - 7 oximineacid/kerosene system. Through the methods of slope and saturation extraction, the composition of the extracted species also been determined. The eXtraction equilibrium constant iscalculated. From the experimental results and the IR spectra, the possible structure of theextracted species is suggested.
