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.
