摘要 研究了钇与间羧基偶氮氯膦的β型显色反应和各种因素的影响,探讨了显色时间、介质酸度和试剂浓度在α-β转化反应中的作用和规律,确定了β型钇配合物的最佳形成条件和组成。发现β型显色反应存在着两种类型,并提出区别该两种类型反应的判据。 type chromogenic reaction of yttrium wnith chlorophosphonazo-m-k and the influence of various factors on the reaction have been studied in this paper.Action and rule of elapsing time, medium acidity and the reagent concentration on the reaction of the variation from α-type to β-type chelate have been disccussed.The optimum conditions forming the β-type chelate of yttrium have been found and the composition of the β-type chelate has been established.Both kinds of β-type chromogenic reaction have been discovered and the criterion of dis nguishing them has been advanced.
