摘　　要：提出了金属配合物催化对苯二酚(HQ)氧化反应的动力学数学模型.按照文献方法合成了两种不同配体的金属铜配合物,研究了它们在水溶液中以及在阳离子表面活性剂CTAB胶束中催化过氧化氢氧化HQ的反应.研究结果表明,提出的动力学模型具有合理性,胶束微环境对金属铜配合物催化过氧化氢氧化HQ的反应有较大的影响.A kinetic mathematic model for the oxidative reaction between HQ and H2O2 catalyzed by the copper(Ⅱ) complexes was proposed. The two copper(Ⅱ) complexes were synthesized according to the literature. The HQ oxidation with the peroxide hydrogen catalyzed by the copper(Ⅱ) complexes in water and the micellar solution was investigated.The kinetic data were treated quantificationally by using the kinetic model proposed in the paper. The studied results show that the kinetic model proposed in the paper is reasonable and the micellar effect is evident.
