摘要

采用复合镀丁艺制备负载纳米TiO 的三维镍网，研究开发出已实际工程应用的光催化水处理器，并模拟在不同条件下，对活性黑GR溶液进行降解脱色实验研究，获得最佳的实际工程工艺条件和参数．实验表明，uV／镍网／TiO，组合模式对活性黑的降解效果最佳，在240 rain内脱色率能达到94．76％．活性黑溶液的脱色率随初始质量浓度的增大而减小，当质量浓度为20 mg／L时，降解效果最佳，处理240 rain脱色率能达到98．35％；活性黑溶液pH=5时，脱色率能达到94．2％；投加1 g／L H 0 增强了光催化降解效率，在150 min内，脱色率能达到98．6％．

Abstract

It studies the degradation of reactive black dye by using engineering photocatalytic reactors coated with nanoscale TiC2 under different experiment conditions to gain the optimal parameters for the real pr~ect．Results indicate that the combined mode of UV／Nicke1．Net／TiC，has the highest degradation efficiencv for reactive black dye，and that the percent age of decolorization may achieve 94．76 ％ in 240 min．With the increase of the initial concentration of the dye，the percent age of decolorization will decline obviously．When the initia1 concentration is 20 mg／L，decolorization percent is more than 98．35％ after 240 min reaction period． Better degradation effect could be got under the condition of pH value equal to 5．reaching 94．2％．The degradation process can also be controlled by adding H2 O2，and when the content of H2 02 is l g／L，decolorization percentage can reach up to 98． 6 ％ after 1 50mins’treatment．
