| 摘 要： | 盐效应是个应用广泛的概念,在化学相关学科中存在不同释义。现在出现一些对盐效应概念的曲解外延,如在化学交叉学科中出现"正盐效应"的提法;也出现"盐效应有时又叫非共同离子效应"的提法。不是盐的酸、碱、有机物等也可作为盐析剂,许多超出盐效应概念界定范围的同质现象出现,反映盐效应有一定局限性。通过盐效应在国内发展途径与适用例的回顾与辨析,提议统一盐效应。

| Abstract: | As a widely used concept salt effect is presenting different interpretations in some related subjects in chemistry.Some extensive misinterpretations on concept of salt effect have appeared.The examples are the appearance of the term as "positive salt effect" appeared in chemical interdisciplinary subjects and the statement that "salt effect sometimes can be called as non common ion effect".It could seen from the appearance of many identical quality phenomena which exceed the defined range of salt effect such as non-salt substances as acid,base and specific organic chemicals could be act as salting-out agent that the definition of salt effect is presenting certain limitations.With the review of the development route of the concept-salt effect in China and the analysis of some adaptable examples,the suggestion for the unification of salt effect has proposed. |
