摘要： 用两相充分混合法,在298±1K下研究了HEH[EHP]-正庚烷-1.0mpL·L-1(Na,H)NO3体系中萃取Fe(Ⅲ)的动力学过程。认为界面慢反应为速率控制步骤。

Abstract: The extraction kinetics of the system Fe(Ⅲ)/1.0mol.L-1(Na,H)NO3/ HFH[FHP]-heptane has been studied at 298±1K with highly stirred tanks. The change of concentration of Fe(Ⅲ) in the aqueous phase with the extraction time is determined by potentiometry.

Key words: Extiaction kinetic, Isron(Ⅲ), Mono(2-ethylhexyl) 2-ethylhexyl phospho- nic acid
