摘要
热色性迟后现象在固相体系中已有过研究，但在液相体系中尚未见诸报道．为此用分光光度法研究了镧系元素离子Ｌａ（Ⅲ）和Ｇｄ（Ⅲ）的二甲酚橙（简称ＸＯ）螯合物水溶液在Ｎ，Ｎ—二甲基甲酰胺（简称ＤＭＦ）影响下的热色性迟后现象．研究表明，ＤＭＦ对镧系元素离子Ｌａ（Ⅲ）。
Lag of thermochromism have been studied in the solid phase systems, but have not been in the liquid phase. The lag of thermochromism of Ln(Ⅲ)-XO chelates aqueous solutions in DMF were investigated by spectrophotometry in this paper. The results showed that DMF obviously affected on the lag of thermochromism of these compounds.
