Abstract
The transportation and separation of Cu(Ⅱ) through a dispersion supported liquid membrane(DSLM) consisting of 2-ethylhexyl Phosphonic Mono-(2-Ethylhexyl) in kerosene, supported on the polyvinylidene fluoride membrane(PVDF), is studied. The effects of pH value in the feed phase, volume ratio of liquid membrane phase and hydrochloric acid, concentrations of HCl in the strip phase and initial concentration of Cu(Ⅱ) in the feed phase are also researched. The results show that copper ion can be transported effectively when pH =5.25 in the feed phase, the volume ratio is160:40, concentrations of HCl in the strip phase is 4.0mol/L. Under the optimum transport conditions, when initial concentration of Cu(Ⅱ) was 2.00×10-4mol/L, the transport rate of Cu(Ⅱ)was up to 94.7% in 130 min.
