N2 - This work reports adsorption and catalytic oxidation process for degradation of hexamine (HMT)-containing industrial wastewater based on the reduction in total organic carbon. The studied systems include hydrogen peroxide, MCM-41, phosphotungstic acid (PTA)/MCM-41 embedded via impregnation method, PTA/H2O2 and PTA/MCM-41 embedded via impregnation or direct synthesis methods in the presence of hydrogen peroxide. The TOC results indicated that the system including PTA embedded within MCM-41 via direct synthetic method in the presence of H2O2 has a higher performance for degradation of HMT-containing wastewater. The total organic carbon for the mineralization of HMT was obtained to be 57%, under optimum conditions.
