Factors including light sources, pH, irradiation time and the usage of catalyst that influenced the process were investigated. The technique established has been employed for the treatment of EB present in discharged water and electrophoresis gel with satisfied result, indicating that this method is not only simple, but also effective, and can be possibly applied in practice.展开更多
采用均匀沉淀法制备了锐钛型二氧化钛,然后在适当酸度、DBS浓度、处理温度及反应物浓度环境下将二氧化钛进行了处理,对处理后样品进行了XRD、N_2吸附、粒度分析表征样品的结构、晶体形貌、物性情况及粒度分布情况,发现二氧化钛物性情况...采用均匀沉淀法制备了锐钛型二氧化钛,然后在适当酸度、DBS浓度、处理温度及反应物浓度环境下将二氧化钛进行了处理,对处理后样品进行了XRD、N_2吸附、粒度分析表征样品的结构、晶体形貌、物性情况及粒度分布情况,发现二氧化钛物性情况有较为明显的改善,处理后的TiO_2样品比表面积达346 m^2·g^(-1),孔容达0.31 m L·g^(-1),TiO_2粒子平均粒径不大于10 nm。展开更多
