溴化氧铋（BiOBr）光催化降解橙黄域的研究
Study on photocatalytic degradation of orangeII by BiOBr
摘要
Abstract
This paper introduces the photocatalytic degradation of the orangeIIby BiOBr under UV irradiation. By changing the experimental conditions such as the concentrations of reaction solution, pH, amount of catalysts and intensity of illumination the authors study the major influence factors of the reaction system; active substances and main oxidative species are determined through adding various free radical scavengers; adding halogen elements helps understand the effect of halogen elements on photocatalytic degradation of orangeII. The experiment results show that, changes of the experimental conditions have different degrees of impacts on the experiment;the hole is the main oxidizing species in the reaction system while the halogen elements do not compete with main active substance of degradation of orangeIIdirectly, thus they have little influence to the experiment.关键词
