【摘要】 全氟化合物(perfluorinated compounds,PFCs)是一类人工合成的难降解有机污染物.PFCs长期大量使用导致其在水环境中普遍存在,并且已在人体中检出.传统的生物处理技术对PFCs几乎没有去除效果,研究高效去除水体中PFCs的实用化技术成为了环境领域的研究热点.本文综述了电化学氧化、电絮凝和电吸附等电化学技术在PFCs废水处理中的研究进展,详细阐述了不同电化学处理技术对PFCs的去除效率、影响因素以及去除机理,并对今后水体中PFCs电化学去除技术研究提出了展望.更多还原

【Abstract】 Perfluorinated compounds(PFCs) are artificial refractory organic pollutants which are ubiquitous present in various water environmental matrices and have been detected in the human beings. Since the conventional biological-based wastewater treatment methods cannot efficiently degrade the majority of these pollutants, powerful methods for the decontamination of PFCs have received increasing attention. A review of efficient electrochemical technologies developed to removal PFCs for environmental protection is summarized. Fundamentals and main applications of typical methods such as electrochemical oxidation, electrocoagulation and electrosorption are reported. The influence factors on the degradation of PFCs by different electrochemical technologies and the removal mechanisms were discussed in detail. At last, the research prospect of the electrochemical technologies was proposed.更多还原
