摘要
利用恒界面池法研究三烷基氧膦 (TAPO) 煤油从盐酸介质中萃取Ir(Ⅳ )的动力学。测定了水相金属浓度 ,水相氢离子浓度 ,三烷基氧膦浓度 ,温度 ,搅拌速度等对萃取速率的影响 ,并得出萃取速率规律。
The kinetics of the extraction of Ir(Ⅳ) from hydrochloric acid solution with Tri-n-Octylphosphine(TAPO)-kerosene was studied. The effects of the concentrations of Ir(Ⅳ), H +, TAPO, temperature and stirring speed on the extraction rate was examined. The extraction kinetics mechanism of Ir(Ⅳ) by Tri-n-Octylphosphine was studied by Lewis cell. It is found that the process of this extraction is one kind of the chemical reaction controlled system.
