本文基于钇与镧系元素的性质极为相似,而探索了β型钇-偶氮氯膦Ⅲ络合物生成的可能性.结果表明,在一定条件下,钇和重镧系元素一样,能与该试剂生成α型和β型两种类型的络合物.继而研究了各种因素对α-β转化反应的影响.测定了α型和β型络合物的组成.并确定,β型钇络合物在一定浓度范围内符合比尔定律,而为其应用提供了依据. In this paper, based on the very similar properties of yttrium and lanthanides, the possibility of the formation of β-yttrium-chlorophosphonazo Ⅲ complexes was explored.The results show that under the certain conditions, yttrium, like heavy lanthanides, The reagent generated two types of complexes, α and β, and then investigated the effect of various factors on α-β conversion. The composition of α-type and β-type complexes was determined and it was confirmed that β-type yttrium The complex complies with Beer’s law in a certain concentration range, which provides the basis for its application.
