摘要
系统研究了4种(膦类、胂类、羧类、羟类)共11个含氟取代基的不对称变色酸双偶氮类试剂与36个金属离子显色反应的性能。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。探讨了金属离子的种类、性质及试剂分子结构与显色反应性能之间的关系。
A systematic study on colour reactions of
four series of 11 fluorinated asymmetric bisazo
chromotropic reagents with 36 metal ions has been
conducted in detail.The acidity of reactions,
absorption maximum of complexes and reaction
sensitivity were investigated.The relationship
between the molecular structures of the reagents
and colour reaction has been explored extensively,
and a comparison between poly-and monohalo-
genated asymmetric bisazo chromotropic reagents
was performed.
