摘    要:通过实验研究,在Air气速、pH值条件下用自制的载银催化来降解水溶液中的甲基橙,得出如下结论:(1)在本实验条件下,Ag/TiO2催化剂对甲基橙没有明显的吸附作用。(2)甲基橙的降解速率随气速的增大而增大,反映在本实验中就是溶液中甲基橙的浓度不断地降低,但当气速增大到一定值时,溶液中甲基橙的浓度反而增高,这说明气速有一最佳值4L/min。(3)pH值对甲基橙的降解也有一定的影响,实验表明在pH=2的条件下,载银催化剂对甲基橙的降解效果最好。

关 键 词:甲基橙  载银催化剂  光降解  光催化剂  降解速率  Air气速  pH值

Abstract:Through the experimental research, that is, degrading of methyl orange in aqueous solution using Ag/TiO 2 photocatalyst under conditions of air speed and pH value, the following conclusions are reached: 1. Ag/TiO 2 catalyst has not obvious adsorption to methyl orange 2. The degradation rate of methyl orange will become faster as the air speed increases, however, when the air speed rises to a certain degree, the concentration of methyl orange becomes higher. This proves there exists a best value of the air speed: 4L/min. 3. pH value has a definite influence on degrading of methyl orange. Degradation of methyl orange is the most effective under the conditions of pH=2.
Keywords:methyl orange  Ag/TiO2  catalyst  light degradation
