摘要 以聚偏氟乙烯膜(PVDF)为支撑体,煤油为膜溶剂,N-N-二(1-甲基庚基)乙酰胺(N503)为流动载体,研究了分散支撑液膜体系中金属Pd(Ⅱ)的传输行为;考察了料液相酸度、分散相膜溶液与解析液体积比以及分散相中KSCN浓度对Pd(Ⅱ)传输的影响。结果表明,当料液相中盐酸浓度为0.10mol.L-1、分散相中膜溶液与解析液KSCN体积比为30:30、解析液KSCN浓度为1.60mol.L-1时,该分散支撑液膜体系对金属Pd(Ⅱ)具有良好的传输作用。在最佳传输条件下,Pd(Ⅱ)起始浓度为5.00×10-5mol.L-1时,130min的传输时间分散支撑液膜体系传输效率可以达到79.8%,而传统支撑液膜只有67.8%。 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.
