We present a short review of recent computational and experimental studies on surfaces of solutions of inorganic salts in polar nonaqueous solvents. These investigations complement our knowledge of aqueous interfaces and show that liquids such as formamide, liquid ammonia, and ethylene glycol can also surface-segregate large polarizable anions like iodide, albeit less efficiently than water. For liquids whose surfaces are covered with hydrophobic groups (e.g. methanol), the surface-ion effect all but disappears. Based on the present data a general picture of inorganic-ion solvation at the solution-vapor interface of polar liquids is outlined.
我们简要回顾了近期关于无机盐在极性非水溶剂中溶液表面的计算和实验研究。这些研究补充了我们对水相界面的认识，并表明诸如甲酰胺、液氨和乙二醇等液体也能在表面分离出可极化的大阴离子，如碘离子，尽管效率不如水。对于表面覆盖有疏水基团的液体（如甲醇），表面离子效应几乎消失。基于现有数据，概述了极性液体溶液 - 气相界面处无机离子溶剂化的一般情况。
