MWCNT/MNO2 AS A CATALYST FOR THE OZONATION OF ANTIBIOTICS: A KINETIC MONTE CARLO SIMULATION

Kinetic Monte Carlo simulation was used to investigation kinetics of ciprofloxacin degradation by direct and heterogeneous catalytic (MnO2 and carbon nano tube loaded with MnO2) ozonation. The reaction kinetic mechanisms of each systems have been obtained. The rate constants values for the each step of the reaction mechanisms were attained as adjustable parameters by kinetic Monte Carlo simulation. The carbon nano tube loaded with MnO2 plays important role as catalyst in the ciprofloxacin ozonation by increasing reactivity of ozone and ciprofloxacin drug on the surface of carbon nano tube. Optimized amount of ozone and catalysts were obtained via study the effect of inlet ozone concentration and initial amount of catalyst on the rate of ciprofloxacin degradation using Monte Carlo simulation. The simulation results of this study have reasonably agreement with the present experimental data for the ozonation of ciprofloxacin drug.
