Removal of p-toluenesulfonic acid from wastewater using a filtration-enhanced electro-Fenton reactor.

ABSTRACT: Rapid global industrialization accompanies the discharge of industrial wastewater. p-Toluenesulfonic acid (PTSA), a kind of aromatic sulfonate that belongs to the refractory organic pollutant, is one of the most widely used chemicals in pharmaceutical, dye, petrochemical and plastic industries. In this study, we developed a filtration-enhanced electro-Fenton (FEEF) reactor to remove PTSA from synthetic wastewater. A filtration-enhanced stainless-steel mesh (FESSM) was used as the cathode. Under the optimal operating conditions of applied voltage 2.5 V, pH = 3.0, addition of 0.2 mM Fe²⁺ and 1.0 mM H₂O₂ for 120 min, the removal efficiency of PTSA (initial concentration of 100 mg L^-1) could reach 92.6%. Compared with the control anodic oxidat
