The Extraction Behavior of Cu2+ with N,N,N',N'-Tetrabutyl-3-Oxy-Glutaramide from Hydrochloric Acid

Abstract

The extraction behavior of Cu2+ using N,N,N,N-tetrabutyl-3-oxy-glutaramide from hydrochloric acid was studied. The effect of hydrochloric acid concentration, NaCl concentration, extractant concentration, and temperature on the extraction distribution of Cu2+ was also investigated. The result shows that the distribution ratio increases with an increase of the acid concentration, NaCl concentration or extractant concentration, but decreases with temperature, which demonstrates that the extraction reaction is exothermic.
