使用配体1,3,5-三(4-羧基苯基)苯(H_3BTB)通过水热法合成了配合物Co_3(BTB)_2(H_2O)_5(DMF)_9(用Co L表示),经红外光谱和元素分析进行了结构表征。将其用于催化过氧化氢脱色活性艳蓝KN-R,研究了双氧水浓度、催化剂浓度、温度和活性艳蓝KN-R的初始浓度对脱色效果的影响。研究表明,CoL表现出优异的催化脱色性能,在废水处理方面具有广阔的应用前景。

The coordination complex Co3（BTB）2（HEO）5（DMF）9（CoL） based on 1,3,5-benzenetricarboxylic acid （H3BTB） ligand was synthesized by hydrothermal method. The structure was characterized by infrared spectroscopy and elemental analysis. CoL was applied in catalyzing the decolorization of Reactivc Brilliant Blue KN-R by hydrogen peroxide. The decolorization ratios in different conditions were studied in detail, such as the concentration of hydrogen peroxide, the concentration of Co3（BTB）2（H20）5（DMF）9, temperature and Reactive Brilliant Blue KN-R initial concentration. The results showed that the complex had good catalytic activity, which had potential application in wastewater treatment.
