Use of fenton's reagent for removal of pesticides from industrial wastewater

We report in this paper the preliminary results obtained during removal of pesticides from industrial wastewater by Fenton's reagent. Fenton process is attractive alternative to conventional oxidation processes in effluent treatment of recalcitrant compounds. The aim of this study is to evaluate the efficiency of fenton process for the reduction of COD in wastewaters from pesticide industry. Several parameters were also studied: dose of Fe+2 and H2O2. The process of pesticide removal from industrial wastewater using Fenton's reaction has been analysed by taking into consideration COD removal. The optimum ratio of [Fe2+] to [H2O2] was 1: 1,56 (mM/mM) at pH 3.0 and room temperature (20°C). 93 % COD removal was achieved when treated wastewater by Fenton's reagent.
