项目摘要

The effect of bleaching and disinfecting by bleaching agent were examined for keeping up the clean and cheerful life.Peroxide bleaching using hydrogen peroxide or oxidizing enzyme is helpful to protect some environmental problem. Then, decoloration of dyes and disinfecting action to bacterias ( Colibacillus, Staphylococcus aureus ) by glucoseoxidaze at the mild condition such as pH 8, 25℃ were examined. The effect of decoloration rate of C.I. Acid Orange 7 with hydrogen peroxide from glucoseoxidaze catalyzed by peroxidaze was incleased, and depending on the condition, glucoseoxidase has passable sterilizing power. Manganese protoporphyrin or mesoporphyrin derivatives catalyzed decoloration of azo dyes by hydrogen peroxide at the mild condition such as pH 8, 25℃ was examined. The rate was accelerated due to the presence of manganese protoporphyrin or mesoporphyrin derivatives under this condition, depending on the structures of manganese porphyrins and azo dyes. Interestingly, the rate depended on the concentration of ligands, in which imidazole plays an crucial role on the rate. Kinetics on the decoloration rate of azo dyes by hydrogen peroxide catalyzed by polyethylene glycol - linked manganese porphyrin derivatives were made, indicating that the complex forming between the azo dye and manganese porphyrins with hydrogen peroxide played an important role on the difference of rate between azo dyes.

为了保持人们清洁愉快的生活，对漂白剂的漂白和消毒效果进行了研究，并对用过氧化氢或氧化酶进行过氧化氢漂白有助于保护环境问题进行了探讨。在pH8，25℃的温和条件下，考察了葡萄糖氧化酶对染料的脱色及对大肠杆菌、金黄色葡萄球菌的杀菌作用。研究了影响C.I.利用过氧化物酶催化葡萄糖氧化酶生成的过氧化氢生成酸性橙子7，在一定条件下葡萄糖氧化酶具有一定的杀菌能力。研究了锰的原卟啉或中卟啉衍生物在温和条件下（pH 8，25℃）催化过氧化氢对偶氮染料的脱色作用。在此条件下，由于锰原卟啉或中卟啉衍生物的存在，该速率加快，这取决于锰卟啉和偶氮染料的结构。有趣的是，该速率依赖于配体的浓度，其中咪唑起着至关重要的作用的速率。研究了聚乙二醇连接的卟啉锰衍生物催化过氧化氢偶氮染料脱色的动力学，结果表明，偶氮染料与卟啉锰与过氧化氢形成络合物是导致偶氮染料脱色速率差异的重要原因。
