一、前言自从羟肟类螯合型萃取剂应用于大规模工业生产以来,萃取动力学的研究受到了很大的重视,成为当前萃取化学中的一个新的较为活跃的领域。由于这类萃取剂萃取铜的速度较慢,开展萃取动力学的研究,搞清萃取反应的机理,从而采取有效的措施,(如添加动力学协萃剂, I. Introduction Since the application of the hydroxyoxime chelate-based extractant in large-scale industrial production, the extraction kinetics has drawn great attention and has become a new and more active field in the current extraction chemistry. Due to the slow extraction speed of copper from these extractants, the study on extraction kinetics and the mechanism of extraction reaction are conducted to take effective measures (such as adding kinetic synergist,
