摘要
采用液相光催化,通过不同浓度的负载型光催化剂对不同分散剂分散下的混凝土基材降解常见的亚甲基蓝(MB)溶液进行分析,研究前后吸光度的变化,并用标准曲线换算出浓度的变化,得出浓度变化的评价,从而定性得出光催化混凝土的降解性能分析。
In this paper,liquid-phase photocatalysis is used to analyse the degradation of common methylene blue(MB)solutions of concrete substrates under different concentrations of loaded photocatalysts dispersed with different dispersants,to study the change in absorbance before and after,and to convert the change in concentration using a standard curve to derive an evaluation of the change in concentration and thus qualitatively derive an analysis of the degradation performance of photocatalytic concrete.
