Treatment of aqueous dimethyl phthalate by the combined electrocoagulation/fenton process

In the present study, the treatment of aqueous dimethyl phthalate (DMP) by the combined electrocoagulation/Fenton (EC/Fenton) process was investigated. Compared with plain electrocoagulation, the combined EC/Fenton process proved to be a more effective treatment alternative both considering complete DMP degradation and organic matter removal in terms of mineralization. The proper electrocoagulation operational conditions for the present case were established as follows: initial pH 2.0, applied current density 22 mA/cm², electrolyte concentration 1500 mg/L NaCl, H₂O₂ concentration of 40 mM for aqueous DMP (100 mg/L) solution for the present case.
