A Basic Study On The Organic Dye Degradation By Binao3photocatalyst

Organic degradation by photocatalyst has proven to beone of the best ways to overcome environmental pollution problems. This is because it is low in cost and has high efficiency. Besides, it is easy to employ. In this study, we are conducting a research on other possible materials and their optimum condition that can aid in the organic degradation of dyes, besides the titanium dioxide (TiO2) which is already widely used in treating and degrading the dyes, pesticides and other organic contaminants. Based on the previous study, the bismuth sodium trioxide (BiNaO3) is one of the best photocatalyst in degradation of the dye. Therefore, we further our study in finding the optimum condition for the BiNaO3 in order to have a higher degradation efficiency. The methylene blue (MB) and methyl orange (MO) dye was used as the organic dyes and the experiment was conducted under three different pH conditions (pH 3, 7, 11) with and without the presence of visible light. The result shows that the bismuth sodium trioxide work best under the acidic (pH 3) condition, with the presence of visible light for both dyes. As for the methyl orange (MO) dye, bismuth sodium trioxide took a longer time in degrading the dye compared to the methylene blue (MB) dye. It took only 20 minutes to degrade the methylene blue dye under the presence or without the presence of visible light condition. For the methyl orange (MO) dye degradation, it took about 60 minutes to degrade with the presence of visible light. As a conclusion, bismuth sodium trioxide under acidic solution has been proven as one of the possible photocatalyst in the treatment of the dyes contaminants.
