A kinetic study and application of electro-Fenton process for the remediation of aqueous environment containing toluene in a batch reactor

Resumo

In this work, the degradation and mineralization of toluene (TOL) in synthetic wastewater were studied by electro-Fenton process in a batch reactor. Also the impact of operational factors such as applied current, electrolysis time, concentration of TOL and Ferrous ion have been explored on the removal of toluene. In optimum conditions, the removal efficiency of TOL and total organic carbon (TOC) were 94.5 and 32.3% after 60 min of reaction. Based on the kinetic study the pseudo first-order rate constant for the removal of toluene and TOC was obtained at k = 5.90 × 10^‒2 and 9.8 × 10^‒3 min^‒1, respectively.
