【Abstract】 The effect of three kinds of surfactants on mass transfer in the system of HNO₃ strip-extraction was studied in the modified extraction cell. Experiments showed that without interfacial prompting the mass transfer coefficient was reduced greatly in the process of HNO₃ strip-extraction by adding three kinds of surfactants. Meanwhile, with interfacial prompting the mass transfer coefficient was increased in the process of HNO₃ stripping by adding the anion and the cation surfactant, and was deceased by adding the non-ion surfactant.更多还原
