摘要
设计并合成了三种新显色剂——噻唑偶氮磺酸型化合物。这类试剂可在不同酸度与钯(Ⅱ)配位显色,形成组成为1:1的水溶性配合物。总结了试剂结构和性能之间的关系。
Three new compounds of thiazolyl azo fonic acids have been synthesized. It is found that these com-pounds are good chromogenic reagents for palladium. Thses reagents react with pd in different acidic mediato form water soluble chelates with 1: 1 molar ratio. The sensitivity and selectivity of these reagents arehigher than those published in the literature. The relationship between the structure of these reagents andtheir chromogenic properties has been studied.
