合成了四(4-N-乙基吡啶基)卟啉铁[Fe(TEPyP)],并用紫外-可见分光光度法研究了Fe(TEPyP)分别与表面活性剂正月桂酸肌氨酸钠(LSS)、十六烷基三甲基溴化铵(CTAB)和聚氧乙烯(23)十二烷基醚(Brij35)形成的金属胶束催化H2O2氧化2,4,6-三氯苯酚(TCP)反应的动力学,探讨了体系酸度、H2O2与催化剂的摩尔比以及温度对催化降解反应速率的影响,提出了催化氧化机理,建立了反应的动力学数学模型。结果表明,Fe(TEPyP)和胶束形成的金属胶束表现出过氧化物酶的催化氧化特性,其中阴离子表面活性剂LSS形成的金属胶束的催化作用最显著。
(TEPyP)] was synthesized and the effect of Fe (TEPyP) and surfactant surfactant sodium lauryl sarcosinate (LSS) was studied by UV-Vis spectrophotometry. ), Cetyltrimethylammonium bromide (CTAB) and polyoxyethylene (23) lauryl ether (Brij35) catalyzed H2O2 oxidation of 2,4,6-trichlorophenol (TCP) The kinetics of the reaction, the influence of the acidity of the system, the molar ratio of H2O2 to the catalyst and the temperature on the catalytic degradation rate were discussed. The catalytic oxidation mechanism was proposed and the kinetic mathematical model of the reaction was established. The results showed that the metal micelles formed by Fe (TEPyP) and micelles showed the catalytic oxidation of peroxidase, of which the metal micelles formed by anionic surfactant LSS had the most obvious catalysis.
