Contributing to the study of oxalic acid degradation using TiO2 photocatalyst
Abstract
This study focused on studying the effect of catalytic concentration and UV intensity on oxalic acid decomposition by by photocatalyst using TiO2. Langmuir-Hinshelwood kinetic model was used to monitor the rate of degradation of oxalic acid by TiO2 and UV. The results showed that when conducting the reaction to decompose oxalic acid at 25 oC; 0.5 g/l TiO2 concentration and UV intensity of 100 W / m2, the apparent reaction rate constant kapp= 0.025 minutes-1.
