The objective of this study is to delineate removal efficiency of the MTBE in solution by TiO2 photocatalytic degradation as a function of the following different experimental conditions : Initial concentration of MTBE, air flow rate in solution, H2O2 dosage and pH of the solution.
hotodegradation rate was increased with decreasing initial concentration of MTBE. The removal efficiency was 82% after 180 min in the case of MTBE concentration of 100 mg/L but 100% after 180 min in the case of 20 mg/L. Removal efficiency was increased with increasing pH, H2O2 dosage and air flow rate in solution.
