稀土—铬菁R(ECR)—邻菲哕啉(Phen)—溴化十六烷基三甲铵(CTAB)四元络合物显色反应已有报道,我们发现稀土与ECR、2,2’-联吡啶(dipy)、CTAB可以生成具有更高灵敏度的四元络合物. 由于CTAB对不同稀土络合物的增敏效应不一样,通过改变CTAB用量,使反应的选择性有了较大的改善。因此,我们对RE—ECR—dipy—CTAB四元络合物的形成条件及其有关性能进行了较系统的研究。
The chromogenic reaction of rare earth-chrome cyanine R (ECR) -phenanthrene-cetyltrimethylammonium bromide (CTAB) quaternary complex has been reported. We found that rare earth complexes with ECR, 2,2 ’ -bipy and CTAB can produce quaternary complex with higher sensitivity.As CTAB sensitizing effect to different rare earth complexes is not the same, by changing the amount of CTAB, the reaction selectivity has a larger Improvement. Therefore, we systematically studied the formation conditions of RE-ECR-dipy-CTAB quaternary complex and its related properties.
