以3-硝基邻苯二甲腈为原料合成了α-四(3-羧基苯氧基)酞菁钴,利用IR、UV-Vis、LC-MS和C H N元素分析对催化剂进行了表征.在室温条件下,研究了催化剂用量和H2O2浓度对亚甲基蓝降解效果的影响.当催化剂用量为0.6 g/L、H2O2浓度为6 mmol/L时,80 min后亚甲基蓝的脱色率均可达98.7%.脱色过程符合一级动力学特征,速率常数k=0.039 min-1.重复试验3次,脱色效果可达85%.%A-tetra (3-carboxyl phenoxy) phthalocyanine cobalt was synthesized by 3-nitrophthalonitrile. The catalysts were characterized by IR, UV-Vis, LC-MS and C H N element analysis. The effect of the dos?age of the catalyst and H2O2 concentration on degradation of methylene blue were studied at room tempera?ture. When the catalyst dosage was 0.6 g/L and H2O2 concentration was 6 mmol/L, methylene blue decoloriza?tion rate could reach 98.7% in 80 min. The degradation reaction obeyed first-order dynamic equation, and the rate constant k=0.039 min-1. Repeat the experiment three times, decoloring effect could reach 85%.
