多卤素变色酸双偶氮类试剂与金属离子显色反应性能的研究

Studies on colour reactions of polyhalogenated chromotropic acid bisazo reagents with metal ions

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。

In this paper,systematic study on colour re-actions of three series of 19 polyhalogenated asym-metric bisazo chrgmotropic reagents With 35metal ions has been conducted.Acidity of reac-tion,absorption maxima of complexes and reactionsensitivity were investigated.Relationship betweenthe molecular structures of the reagents and col-our reaction has been explored extensively.
