Enhanced Treatment of Trace Pollutants by a Novel Electrolytic Cell

Abstract

Continuous experiments were conducted to evaluate the electrolytic performance of a novel 3‐dimensional electrolytic cell consisting of granular Pt/Ti electrodes. The electric current efficiency to decompose indigotrisulfonate was approx. 96 %, while energy consumption was one to two orders of magnitude smaller than that for O3 treatment. Furthermore, the cell was successfully applied to treat trace endocrine disrupting chemicals (EDCs) and chlorinated compounds. Energy consumption was in the range of 2 to 10 Wh/m3. From these results, it was concluded that the present electrolytic cell would be a feasible alternative to conventional oxidation processes in water treatment.

“…Compared with the chemical or biological methods, the electrochemical technique for removing organic pollutants has few or no harmful effects on the environment, it is more independent conditions of wastewater [13,14]. Recently, many attempts have been made to study the electrochemical removal of BPA using various electrodes such as Pt/Ti [15,16], SnO 2 /Ti [17], Au [18], carbon fiber [19,20], and boron-doped diamond [21]. Fenton's reagent generated by an electrochemical technique has been used for the degradation of BPA [22].…”
