| 摘 要： | 合成了水杨醛缩牛磺酸席夫碱合铜配合物,研究了该配合物分别在阴离子表面活性剂十二烷基苯磺酸钠(SDBS)、阳离子表面活性剂十六烷基三甲基溴化铵(CTAB)和非离子表面活性剂辛基酚聚氧乙烯醚(OP-10)的胶束中对H2O2分解的催化性能,探讨了pH、过氧化氢浓度对催化性能的影响。结果表明:该配合物在阳离子胶束中对H2O2的分解具有快速催化作用,其催化速率远远高于铜离子本身的催化速率,而且在碱性介质中催化速率明显提高;非离子和阴离子表面活性剂胶束对配合物的催化有禁阻作用。

| Abstract: | Cu complex of taurine-salicylic schiff base was prepared.Catalytic activity of the complex in the micelles of(different) surfactants(SDBS,CTAB or OP-10)for decomposition of H_2O_2 was investigated.The effects of different(conditions)(such as pH and concentrations of H_2O_2)were also investigated.The results showed that,this Cu complex in the micelle of cationic surfactant can quickly catalyze the decomposition of H_2O_2,the decomposition rate of H_2O_2 catalyzed by the complex was much higher than by Cu~(2 ) itself,and basic solution was helpful to the decomposition of H_2O_2.On the contrary the catalytic activity of the complex is hindered in the micelle of non-ionic or anionic surfactants. |
