用光度法、红外光谱法和核磁共振法研究了磷酸三丁酯(TBP)从硫酸溶液中萃取磷钼酸(MPA)的萃取行为和机理。测定了萃取络合物的组成并认为萃取过程中在TBP与MPA之间存在给-受体相互作用的配位机理。
The extraction behavior and mechanism of extracting phosphomolybdic acid (MPA) from sulfuric acid solution of tributyl phosphate (TBP) were studied by spectrophotometry, infrared spectroscopy and nuclear magnetic resonance. The composition of the extraction complex was determined and the coordination mechanism of the donor-acceptor interaction between TBP and MPA during extraction was considered.
