Abstract

Comparison between photocatalysis and sonophotocatalysis were performed in lab-scale experiments for the treatment of benomyl. The effect of operational parameters, i.e., initial benomyl concentration, $TiO_2$ concentration, $H_2O_2$ concentration on the degradation rate of aqueous solution of benomyl has been examined. The optimal conditions for photocatalysis and sonophotocatalysis processes were determined: initial Benomyl concentration was 3 mg/L, the concentration of $TiO_2$ was 2 g/L and $H_2O_2$concentration was 1.5 mM. Under the optimal conditions, sonophotocatalysis was effective for inducing faster degradation of the benomyl.
