Abstract:The transportation of Pd((II) through a dispersion supported liquid membrane (DSLM) system consisting of N, N di(1-methylheptyl) acetamide (N503) in kerosene, supported on the polyvinylidene fluoride membrane(PVDF), was studied. The effects of HCl concentration in the feed phase, the volume ratio of liquid membrane phase to stripping phase, and KSCN concentration in the stripping phase were also researched. The results show that palladium ion can be transported effectively when the HCl concentration in the feed phase is 0.10 mol·L-1, the volume ratio is 30:30, and KSCN concentrations in the stripping phase is 1.60 mol·L-1. The transport rate of Pd(II) can reach to 79.8% through DSLM, while it is only 67.8% through traditional SLM, under the optimum condition of 130 min transport time and initial Pd(II) concentration of 5.00×10-5 mol·L-1.
