摘要: Humic acids (HA) are a potential hazard to aquatic ecosystems and human health. Because biological treatment of contaminated water does not satisfactorily remove these pollutants, novel approaches under evaluation. This work explores electrochemical oxidation HA in aqueous solution lab-scale apparatus using platinum-coated titanium electrodes. We evaluated the effects concentration, current density, chloride concentration ionic strength on rate oxidation. The initial reaction method was used for determining law degradation. results showed that first-order relative density. An appreciable effect also observed, most likely due polyanionic character HA. propose kinetic model fits experimental data.
