| Abstract | Clay material is used as a catalyst to degrade an organic pollutant,. This study focused on the O-cresol oxidative degradation in aqueous solution by adding H2O2 and Mont-Na. The catalytic tests showed a high catalytic activity of Mont-Na, which made it possible to achieve more than 84.6% conversion after 90 minutes of reaction time at 55 °C in 23.2 mM H2O2. The pH value was found to be negatively correlated with the degradation rate of Ocresol. UV-Vis spectrophotometry revealed that the increase of degradation rate at low pH is A cc ep te d A rt ic le This article is protected by copyright.

In addition, the content of iron in Mont-Na decreased after the catalytic test, bringing further evidence about the O-cresol catalytic oxidation. The mineralization of O-cresol is also confirmed by the different methods of characterization of Mont-Na after the catalytic oxidation test. The effect of the O-cresol oxidation catalyzed by natural clay is significant. |
