摘要
镉试剂是光度法测定镉、汞、银、铜等金属离子的优良显色剂,为了改善其分析性能,对其分子结构进行了改造,将其分子中的强吸电子基-NO2换成强给电子基-N(CH3)2,合成了一种新的三氮烯试剂1-(p-N,N-二甲基氨基苯基)-3-(p-苯基偶氮苯)三氮烯,其结构经红外光谱得到了证实。
The cadion is a good chromogenic reagent of spectrophotometric determination of Cd (II), Hg (I) and Cu (II) etc metal ions. In order to improve its spectrophotometric analytical properties, the molecule structure are reformed, strong attractive electron radical --NO_2 of molecule are transferred into strong supply of electron radical (CH_3)_2 --, a new triazene reagent 1- (P-N, N-dimethy 1 amino benzene ) -3 - (p-benzene-azo-benzene) triazene are synthe sed. The structure of related compounds was identified by IR.
