A comparison of electrochemical oxidation performance

The degradation efficiency of organic pollutants in an electrochemical oxidation process depends on the activity of the anode materials (Zhao et al. 2014).Besides high activity, high chemical stability is one of the basic features for the optimal electrode. Typical anode

Electrochemical degradation of trichloroethylene in

2016/3/1In this study, we tested the use of the bipolar electrodes to enhance electrochemical degradation of trichloroethylene (TCE) in an undivided, flow-through electrochemical reactor. The bipolar electrode forms when an electrically conductive material polarizes between feeder electrodes that are connected to a direct current source and, therefore, creates an additional anode/cathode pair in the

Degradation of folic acid wastewater by electro

This study has demonstrated that the electric-Fenton method using a three-dimensional electrode is an efficient method for the degradation of folic acid. The reaction process takes place without adding H 2 O 2 and only needing one addition of Fe 2+ ; then Fe 2+ can be obtained by Fe 3+ and this reduces the formation of iron mud.
