modeling evaluation of carbaryl degradation in a continuously stirred tank reactor by anodic fenton treatment anodic fenton treatment aft has been shown to be effective in removing pesticides from aqueous solution in batch reactors with the formation of less toxic and more biodegradable products to facilitate practical application of aft carbaryl degradation in a continuously stirred tank reactor cstr by aft was investigated under different experimental conditions such as carbaryl inlet concentration fenton reagent concentrationratio and carbaryl feeding flow rate a higher fe2 delivery rate and h2o2 to fe2 ratio h2o2fe2 were found to favor the carbaryl degradation process whereas flow rate was shown to be a much less significant factor to influence the degradation rate under the evaluated experimental conditions a kineticbased semiempirical model was developed to simulate the experimental data and a very good fit between the model and the raw data was found r2 099 a dimensionless parameter kq2 was found to be a good indicator of the degradation rate that is the higher the kq2value is the faster the degradation process is the rate parameter k can be used to evaluate the degradation rate when the flow rate is invariant for a given pesticide the shape parameter beta is most likely related to the availability and reactivity of fenton reagents and hydroxyl radicals to compare the degradation rate of different pesticides more information other than kq2 k and beta values such as the instantaneous degradation rate vs time relationship needs to be considered
