| Abstract: |
| An emulsified liquid membrane system,which includes carrier(P507),surfactant(SPAN80),film strengthening agent(liquid paraffin),solvent(kerosene) and internal phase(H2SO4),was used to extracte indium in the acid leachate of blast furnace dust.The main technique parameters and the factors affecting the extraction efficiency of indium and the stability of the emulsified liquid membrane such as pH of external phase,volume ratio of membrane to internal phase,volume ratio of emulsion to water and time of contact ... |
