Abstract
The present study suggests the approach to select the optimal p-BQ concentration using it as the radical absorber for the catalysts research. It is stated the p-BQ can be subjected to changes during the experiment. It can cause the significant effect on the research results. The impact factors affect the intensity and coloring of the p-BQ. The optimal p-BQ concentration is determined using the photocatalyst based on the alkali earth metal bismuthate during the research.
