摘要: In order to degrade the macromolecular pollutant of humic acid, powder ordered mesoporous carbon (POMC, average pore diameter 4.29 nm) was first applied for preparing granular OMC (GOMC, Φ × H = 4 × 3–6 mm) as electrodes in a continuous three-dimensional (3D) electrochemical system. The POMC synthesized by hard-templating method and characterized using scanning electron microscopy (SEM), transmission (TEM), particle size distribution, N2 adsorption/desorption technology, Fourier-transform infrared (FT-IR). effects degradation parameters, such current hydraulic retention time (HRT), were investigated, mechanism HA explored well. results indicated that efficiency HA, chemical oxygen demand (COD), total organic (TOC) reached 95.3, 86.2, 62.7%, respectively, under initial 100 mg/L, 0.2 A, HRT 130 min. detection paramagnetic resonance (EPR) showed plenty ˙OH generated on GOMC electrodes, which made 3D system more effective than conventional two-dimensional (2D) cyclic voltammetry curves reactions materials surface included both direct oxidation reduction.
