摘　　要：本文系统论述了羧酸类捕收剂改性研究进展及其作用机理。在羧酸的非极性基上引入氟、氯、磺酸基、硫酸根、羧基、硝基和羟基等极性基团，把氮、氧等具有孤对电子的原子以及多个氧乙稀基团通过缩合等反应加到羧酸的非极性基上。A systemtic description is made of the modification study of carboxylic acidcollectors and their action mechanism. Their collecting property can be improved by:1)adding such polar groups as -F,-SO_3,-SO_4,-COOH,-NO_2 and -OH to carboxylicacid’s nonpolar groups; 2) adding atoms with isolated pair electrons,such as Ni and O,andoxyethylene groups to carboxylic acid’s nonpolar groups by chemical reaction,such as con-densation and 3) forming bipolymer or trimer by electrochemical or ultra-sonic treatment ofcarboxylic acid solution.
