However, these substances may co-exist in water bodies and soil environment, which may be toxic to aquatic species. Disinfection by chlorine is a typical process in drinking water and wastewater treatment. These compounds are easy to react with free chlorine due to the presence of the amine group. The cheapest way to produce free chlorine is the electrolysis of sodium chloride solution. If the wastewater containing enough chloride, electrochlorination may be an effective way for amine-containing substances removal. The chloride ions are first oxidized to chlorine and then hydrolyzed to hypochlorous acid (HOCl) or hypochlorite ion. Nevertheless, no studies have been investigated about electrochlorination of pharmaceuticals in different anodes with the systemic report about energy consumption. The main goal of this work will be evaluated the degradation of pharmaceuticals by electrochlorination. The influences of various operational parameters, such as the anode materials, geometry characteristic, initial pH, and the role of free chlorine on the electrochlorination performance will be investigated in deionized water and real domestic wastewater for the optimization of the pharmaceuticals removal efficiencies. Finally, the feasibility of the continuous electrochlorination systems will be accessed by an indicator of energy consumption.電氯化法電化學氧化法自由氯極板幾何特性藥物ElectrochlorinationElectrochemical oxidationFree chlorineGeometries of electrode platePharmaceuticals
