摘 要：<正> A kind of Levextrel resin separation process was developed for separation of indium （Ⅲ）, gallium （Ⅲ）, and zinc （Ⅱ） from aqueous sulfate solution with Levextrel resin containing di（2-ethylhexyl） phosphoric acid （CL-P204）. The aim of the research is to collect preliminary results for a pilot-scale production. Properties of adsorbing indium （Ⅲ）, gallium （Ⅲ）, and zinc （Ⅱ） from sulfate solution with the Levextrel resin were first studied by batch operation and column operation. The optimum pH, adsorption capacities and concentrations of stripping agents for indium （Ⅲ）, gallium （Ⅲ） were tested. The separation order of indium （Ⅲ）, gallium （Ⅲ）, and zinc （Ⅱ） from sulfate solution with CL-P204 Levextrel resin was found that indium （Ⅲ） could be first separated by adsorbing at the acidity of 1.0 mol/L whereas gallium （Ⅲ） and zinc （Ⅱ） could not, and they were adsorbed together by adsorbing at pH = 2.8, then separated from each other by stripping with 0.1 and 0.5 mol/L hydrochloric acid, respectively.
