摘　　要：在两种稀释剂体系中研究了N,N,N',N'-四丁基-3-氧戊二酰胺(TBOPDA)从盐酸介质中萃取铁离子的性能和反应机理。考察了水相盐酸浓度、萃取剂浓度及温度对其萃取性能的影响。实验结果表明分配比随盐酸浓度的增加而增加;随萃取剂浓度的增加而增大;萃取过程为放热过程,升高温度不利于萃取。The extraction performance and mechanism of Fe（ Ⅲ ） withN,N,N′,N′＇-tetrabutyl -3 -oxy- glutaramide were studied in two diluents . The influence of the concentration of hydrochloric acid, TBOPDA and the temperature on the extraction had been investigated. The results showed that the extraction distribution ratio of Fe （Ⅲ） increased with the increase of the concentration of hydrochloric acid. Extraction distribution increased with the increase of extractant concentration. The distribution ratio decreased with the increase of temperature, and the extraction reaction was exothermie.
