摘要:
以三辛胺为络合剂、甲苯为稀释剂对苯乙酸水溶液进行络合萃取研究,主要探讨了萃取过程中的平衡常数、盐效应、热效应及光谱学行为.结果表明,萃取过程存在离子缔合成盐和氢键缔合溶剂化两种机理,同时无机阴离子对苯乙酸的络合萃取具有竞争作用,基于可逆化学反应的络合萃取对苯乙酸溶液具有高效性和高选择性.
Abstract:
Phenyl acetic acid in waterwas extracted based on chemical comp lexion and the extraction mechanism of phenyl acetic acid was studied. The paper also discussed certain factors that influence the extracting efficiency. The results showed that both hydrogen bonding and ionization existed in the comp lex formed by TOA and phenyl acetic acid, and ion2pair association wasweakened by inorganic anion competition. This technique was of characteristic of high capacity and high selectivity.
