杯冠化合物在处理高放废液中的应用(Ⅱ)——稀释剂对异丙氧基杯4冠6萃取性能的影响

Novel Extractant Calixcrown Used in High-level Liquid Waste(Ⅱ)——Extractive Capability of Bis(2-propyloxy)calix4crown-6 in Different Solvents

摘要: 选择了15种单一稀释剂和4种混合稀释剂,分别研究它们对异丙氧基杯4冠 6的溶解性能和在不同酸度下对异丙氧基杯4冠 6萃取铯的影响。研究结果表明:正辛醇、苯甲醇、环己酮、硝基苯基甲基醚做稀释剂时可较好萃取铯离子,萃取体系对于模拟高放废液中其它离子的萃取率很低。

Abstract: The distribution coefficient of cesium by bis(2-propyloxy)calix4crown-6 in fifteen pure and four mixed diluents is studied. When bis(2-propyloxy) calix4crown-6 is dissolved in octylalcohol, benzyl alcohol, cyclohexanone and 1-methoxy-2-nitrobenzene, respectively, the extractive performance is good.
