近年来,溶剂萃取动力学的研究已日益引起人们的重视。这主要是由于在核燃料和一些重要金属的萃取分离工艺中正在广泛地采用离心萃取技术,一些螯合型的萃取剂(如LIX-64)对铜等有色金属的萃取已成功地在工业中大规模应用。同时,有关萃取的基础理论研究也正在从平衡状态深入到动力学和传质过程。目前研究萃取动力学的方法不少, In recent years, the research of solvent extraction kinetics has drawn more and more attention. This is mainly due to the widespread use of centrifugal extraction technology in the extraction and separation of nuclear fuels and some important metals. The extraction of non-ferrous metals such as copper by chelating extractants (such as LIX-64) has been successfully used in industry Scale application. At the same time, basic theoretical research on extraction is also going from equilibrium to kinetics and mass transfer processes. At present, there are many ways to study extraction kinetics,
