摘要/Abstract

摘要： 对染料活性艳红X-3B水溶液的光催化反应过程进行了初步研究.首先,利用紫外-可见吸收光谱、高效液相色谱和质谱对反应过程中溶液组成的变化进行了测试,并用重铬酸盐法测定了各反应时刻溶液的COD值;其次,使用红外吸收光谱对反应过程中催化剂表面的吸附物种进行了考察.研究结果表明,在本实验条件下,活性艳红X-3B水溶液的光催化脱色和矿化过程是同时进行的,脱色反应完成后,溶液中生成了难以降解的中间产物,致使矿化过程难以继续进行.

关键词: 光催化, 活性艳红X3B, 脱色反应, 矿化过程

Abstract: The photocatalytic reaction of reactive brilliant red X-3B aqueous solution was studied.During the photocatalytic processes,ultraviolet-visible spectrophotometer,high performance liquid chromatograph and mass spectrograph were applied to investigate the composite changes of reactive brilliant red X-3B aqueous solution,and the COD values of reactive brilliant red X-3B aqueous solution were measured by dichromate titration method,the adsorptive species on the surface of catalysts were tested by Fourier transform infrared spectrometer.The results indicated that,the photocatalytic decoloration and degradatin processes were taken place simultaneously under our experimental conditions.Some species which difficult to mineralize were produced in the solution after decoloration process,so that,the mineralization process was difficult to proceed.

Key words: photocatalysis, reactive brilliant red X-3B, decoloration, mineralization
