摘　　要：研究了在硫酸体系中用三正辛胺(TOA)萃取Ge4+的机理,结果表明在水相中加入酒石酸与Ge4+形成较大的络合阴离子Ge(C4H4O6)32-易转入有机相中,经等摩尔法和饱和法确定了萃取Ge4+的机理和萃合物的组成。基于红外光谱的研究,探讨了萃取后配合物的结构。The characteristics of extraction of Ge^4＋ from sulfuric acid medium with TOA in kerosene are investigated. The experimental results show that the complex anion , which formed between the tartaric acid and Ge^4＋ in the water phase, was easy extracted into the organic phase. Through the methods of equimolar and saturation extraction, the composition of the extracted species and mechanics are determined. From the experimental results and the IR soectra, the possible structure of the extracted species is suggested.
