摘要
用分光光度法测定了在２５℃条件下，以ＮａＣ１Ｏ４为支持电解质的水溶液中，Ｍｎ（Ⅱ）－ＰＡＲ、Ｃｏ（Ⅱ）－ＰＡＲ显色反应的离子强度效应，考察了当溶液离子强度Ｉ＝０．２１～２．０２时，显色化合物的摩尔吸光系数的变化。
In the NaClO 4 H 2O system the ionic strength effection on Co(Ⅱ)-PAR and Mn(Ⅱ)-PAR chromogonic reactions at 25℃ was determined by spectrophotometric method. The change of molecular absorption coefficient for the ionic strength of solution supported by NaClO 4 between 0.20 to 2.02 was investigated. The coeficients of thermodynamic molecular absorption were obtained.
