Degradation of aqueous solution of 4-Chloro-2-Nitrophenol in nano-TiO2/H2O2 system abstract
The present work is focused on the degradation of 4-chloro-2-nitrophenol in aqueous solution containing nano titanium dioxide, hydrogen peroxide and the combination of nano-TiO2/H2O2. The effect of experimental parameters, such as the amount of nano- TiO2 concentration of H2O2, initial concentration of 4-chloro-2-nitrophenol and pH on the reaction was investigated. Experimental data obtained under different conditions describe the dependency of degradation rate on the above mentioned parameters. The optimum conditions of the degradation treatment were: [H2O2]=100 mg/L; [nano- TiO2]=0.004 g/250 mL; initial pH=10 and initial 4-chloro-2-nitrophenol concentration=15 mg/L. Consequently, kinetic parameters were experimentally determined and a pseudo-first-order kinetic was observed.
