| 英文摘要 | Stripping dispersion hollow fiber liquid membrane system (SDHFLM) containing feed phase adding acetate buffer solution and dispersion solution with HNO3 solution as the stripping solution and membrane solution of 2-ethyl hexyl phosphoric acid-mono-2-ethylhexyl ester (PC-88A) dissolved in kerosene, has been studied for the extraction of Sm3+. Many factors including pH value, volume ratio of membrane solution to stripping solution (O/W) and carrier concentration on Sm3+ extraction were investigated. Experimental results indicate that the optimum extraction conditions of Sm3+ were obtained as that PC-88A concentration was 0.120 mol/L, and O/W was 1.00 in the dispersion phase, and pH value was 4.80 in the feed phase. When initial Sm3+ concentration was 1.20 x 10(-4) mol/L, the extraction percentage of Sm3+ was up to 92.8% in 160 min. (C) 2011 Liang Pei.
