| Abstract: | The separation and extraction of copper ion by the system of span80(sorbitan monooleate)-p-amino-phenylsulfonic acid(APS)-NH3 was studied.The optimum conditions were established.The stirring speed for emulsification was 3 500r/min.The emulsifying time and mixing time of emulsion and external phase solution were 10min and 20min,respectively.The ratio of emulsion to water was 0.38. The concentration of APS,span80and paraffin were 11%,4.4% and 2.2%,respectively.The concentration of NH3in internal phase and HCl... |
