酰胺类萃取剂的模糊聚类分析

FUZZY CLUSTER ANALYSIS OF N,N'-DISUBSTITUTED AMIDES

萃取剂的结构与其萃取性能(如分配比、分离比、萃取热力学常数)相关,但因研究对象的繁纷复杂以及所研究的对象的关系中的不确定性,采用精确关联的方法有一定困难。作者曾将模糊聚类分析的方法用于中性磷类萃取剂,本文再次将这一方法用于酰胺类萃取剂。

The method of fuzzy mathematies is used in elustering N,N'-disubstituted amides RCON(R')R' in terms of their behaviour in extraction of U(Ⅵ),Pu(Ⅳ)and HNO_3. The fuzzy clustering results indicate that the extraetion behaviour of N,N'-disubstituted amides are determined by the substitutents R,R' and R'in amides,among these the role of R is more important.The study shows the feasibility of applying the fuzzy mathematies method to study the relationship between the structure and extraction behaviour of the extraetants.
