系统地研究了三组(肿类、膦类和羧酸类)共19种含多卤素的不对称变色酸双偶氮类试剂与35种金属离子的显色反应。考察了反应酸度、配合物的最大吸收峰的位置和反应灵敏度等。在更广泛的意义上探讨了试剂分子结构的变化与金属离子反应性能的关系,为设计和研制性能优良的新试剂、扩大此类试剂的应用范围提供了依据。 A systematic study of three groups (swollen, phosphines and carboxylic acids) of a total of 19 multihalogenated asymmetric chromotropic acid disazo agents with 35 kinds of metal ions color reaction. The reaction acidity, the position of the maximum absorption peak and the reaction sensitivity of the complex were investigated. In a broader sense, the relationship between the changes of reagent molecular structure and the reactivity of metal ions is explored, which provides a basis for designing and developing new reagents with excellent properties and expanding the application range of such reagents.
