Oxidative degradation of Methyl Blue and Bromophenol Blue. Kinetics and influencing parameters
View through CrossRef
The degradation of Methyl Blue (MB) and Bromophenol blue (BPHB) by Fenton process, kinetics and some other influencing parameters, was the objective of this study. The degradation was performed in a 150 mL beaker under stirring conditions at pH 3. The kinetics of the compounds degradation was followed by UV-Vis spectrophotometry. It was found that both compounds can be effectively degraded, whereas MB is degraded more rapidly than BPHB. The pH reduced the efficiency of the degradation process, but even at pH 5.2 significant amounts of the both compounds could still be oxidized, due to the pH decrease during the process, probably effected by the carboxylic acids formed during the degradation process.
