项目摘要
We proposed a flow type reactor for IPA degradation in water phase using ozone microbubbles (O3MB) and TiO2 photocatalyst fixed on nonwoven fabric. It was confirmed that decomposition rate of IPA improved by addition of O3MB and the mineralization rate was promoted by TiO2 photocatalyst. As the further research, the optimal condition of the IPA decomposition by O3MB, nonwoven fabric support TiO2, and H2O2 was investigated using a batch type reactor in order to improve the IPA degradation. The influences on IPA degradation, such as the material or shape of nonwoven fabric and molar ratio of H2O2/O3 with or without UV irradiation, were confirmed and the optimal condition was decided in consideration with O3 concentration because it acts as OH radical scavenger. In this process, it was confirmed that OH radicals were main active species, and contributed to improvement in the decomposition rate of IPA and the mineralization rate of its decomposition intermediates.
提出了一种以臭氧微泡(O3MB)和二氧化钛光催化剂固定在非织造布上,用于水相IPA降解的流动型反应器。结果表明,O3MB的加入提高了IPA的分解速率,TiO2光催化剂促进了矿化速率。进一步研究了O3MB、非织造布载体TiO2和H2O2分解IPA的最佳条件,以提高IPA的降解效果。考察了紫外光辐照前后非织造布材料、形状、H2O2/O3摩尔比等因素对IPA降解的影响,并考虑了O3的浓度对IPA降解的影响,因为O3是OH自由基的清除剂。在此过程中,证实了OH自由基是主要的活性物质,并有助于提高IPA的分解速率及其分解中间体的矿化率。
