摘要
采用下降单液滴法研究了２－乙基己基膦酸单２－乙基己基酯从硝酸介质中萃取铥（Ⅲ）的动力学，测定了不同萃取条件下的萃取速率，提出了萃取速率方程，并对萃取机理进行了探讨。
The extraction kinetics of Tm( Ⅲ ) with 2-ethylhexyl phosphonic acid mono2-ethylhexyl ester in nitric acid solution is investigated using descending single drop technique. The effects of the concentrations of Tms3+ ,H+ ,NO, ,P507 and temperature on the extraction rate are examined. The extraction rate equations are proposed ,and the mechanisms of extraction are discussed.
