| 摘 要： | 设计合成了一种基于偶氮水杨醛的酰腙类探针分子,利用紫外-可见(UVVis)吸收光谱考察了其对Fe3+、Hg2+、Ag+、Ca2+、Cu2+、Co2+、Ni2+、Cd2+、Pb2+、Zn2+、Cr3+和Mg2+等12种阳离子的识别作用。结果表明,该探针在DMSO/H2O(体积比8/2)的含水体系中,对Cu2+具有专一选择性比色识别效果;且当加入Cu2+时,溶液颜色立刻由无色变为黄色,而加入其它阳离子则无变化,说明该探针能够实现对Cu2+裸眼检测。

| Abstract: | It turns out the cationic probe based on azo salicylaldehyde acyl hydrazone has a specific selective colori- metric recognition effect to Cu2＋ in DMSO/H20 water system after test of cation recognition effect on 12 kinds of i- ons like Fe3＋ , Hg2＋ , Ag＋ , Ca2＋ , Cu2＋ , Co2＋ , Ni2＋ , Cd2＋ , solution turns yellow when there is Cu2＋ , while the color does the naked eye detection of Cu2＋ with this probe. Pb2＋ ,Zn2＋ not change , Cr3＋ and Mg2＋ through UV - Vis. The when there is other ions, which proves the naked eye detection of Cu2＋ with this probe. |
