| 摘 要： | 本文用激光法测定了过渡金属离子对１％聚乙二醇（ＰＥＧ）水溶液浊点温度的影响，确定了不同浓度，不同金属离子作用下的浊点曲线。结果表明：浊点温度ｔｃ与金属离子质量摩尔浓度ｍ间存在着良好的线性关系。当阴离子相同时，２价阳离子的盐析能力与离子半径、离子势、离子构型以及水合离子构型有关。本文还考查了盐析作用机理。

| Abstract: | The influence of transition metal ions on the cloud point temperature of aqueous PEGwas investigated by using laser method.Cloud point curves were determined for a variaty of trandsitionmetal ions at different concentrations.The results show that there is a linear relationship between cloudpoint temperature To and ionic molalities m. The salting-out power of divalent cations was influencedby ionic radius,ionic potential and hydrated ion configuration |
