摘    要：本文研究了在不同条件下用二-2-乙基已基磷酸—煤油从硫酸盐溶液中萃取镝(Ⅲ)的速度,发现在有足够硫酸根存在下萃取速度变慢。计算了萃取速度常数并提出萃取速度经验方程式。用电子计算机计算了萃取速度随接触时间的变化规律,文中还简要地讨论了影响萃取速度的因素及其机理。

Abstract: The rate of solvent extraction of D_Y (Ⅲ) from Sulphate aqueous solutions with Dis (2-ethyl hexyl) phosphoric acid in kerosene has been studied under different conditions. It has been found that extraction rate is slower in presence of a sufficient amount of sulphate. The rate constant of extraction of D_Y (Ⅲ) has been calculated, and the experi- mental equation of the extraction rate has been provided. The regular changes of the relation between the rate and contact time have been studied with computer progamme. The effective factor of the extraction rate and machanism has also been briefly discussed.
