摘要
电化学技术对水中污染物具有出色的去除效果,在解决传统净水技术的局限性方面有巨大潜力。该文综述了电絮凝、电氧化、电还原和电吸附技术去除水中污染物的原理以及各技术主要电极材料的最新研究进展。指出了在水处理领域电化学电极材料的发展方向,认为未来研究主要集中在产生混合金属氢氧化物絮体、较强吸附性能、具有高催化活性和高稳定性的电极材料上。最后指出了电极材料研究需要面临的挑战。
Electrochemical technology has excellent removal effect on pollutants in water, and has great potential in solving the limitations of traditional water purification technology. In this paper, the principle of electrocoagulation, electrooxidation,electroreduction and electroadsorption technology for removing pollutants in water and the latest research progress of main electrode materials are reviewed. The development direction of electrochemical electrode materials in the field of water treatment is pointed out. It is considered that future research mainly focuses on the generation of mixed metal hydroxide flocs,strong adsorption performance, high catalytic activity and high stability of electrode materials. Finally, several challenges for electrode material research are proposed as well.
