摘要： 近几年来萃取化学基础理论方面的研究不断深入,在广泛的热力学研究的基础上,萃取动力学的研究也日益增多。前文对HDEHP(二-(2·乙基已基)磷酸,用HA表示)萃钙的平衡与机理进行了研究,本文拟对Ca2+,NO3=/HDEHP-萃体系萃取过程动力学加以探讨。

Abstract: The rate and mechanism of extraction of calcium by HDEHP in benzene from nitrate solution have been investigated using the Single Drop Method. The result indicates that the orders of reaction are 1,-1, and 1.5 with respect to [Ca2+], [H+] and [H2A2](o)respectively, and the rate of the reaction depends upon the specific surface of the droplets. The mechanism of the reaction was proposed.
