摘要:

抗生素类药物是目前水环境中出现的一类新兴有机污染物,具有难自然降解、环境刺激性、生物毒性及耐药性等特点,高效去除抗生素类污染物是近年来环境工作者重点探讨的内容。掺硼金刚石(boron-doped diamond,BDD)电极由于自身优异的物理和化学性质,被认作为目前电催化氧化水中有机污染物最为理想高效的阳极材料,但关于BDD阳极在新兴抗生素类污染物的研究情况尚未进行及时的总结。本文首先论述了BDD阳极在电催化氧化有机污染物的降解过程和基于强氧化性物种的电催化氧化机理,进而分析了BDD阳极在电催化降解水中新兴抗生素类污染物的研究进展,探讨了影响抗生素类污染物电催化降解过程的关键影响因素,总结了BDD阳极材料的开发情况,同时,总结了以BDD阳极电催化氧化为基础发展而来的其他水处理联合方法,最后,进一步展望了BDD阳极在未来电催化降解抗生素类污染物存在的问题及未来的重点发展方向。

Abstract:

Antibiotics are considered as a kind of emerging organic contaminants in water environment, which have features of difficult to naturally degrade, environmental irritation, biological toxicity and drug resistance, etc. Therefore, the elimination of antibiotics in water environment has become the focus of environmental researchers in recent years. Benefitting from excellent physical and chemical properties, boron-doped diamond (BDD) electrode has been regarded as the most ideal and efficient electrode material for electrocatalytic oxidation of organic pollutants. However, there is lack of summary for the current research status of BDD anode in emerging antibiotic pollutants. This review firstly discusses the degradation process and mechanisms of organic pollutants involving oxidation species during electrocatalytic oxidation on BDD anode, and then analysis the research progress of electrocatalytic degradation of emerging antibiotic pollutants in recent years. In the following, the key influencing factors on electrocatalytic degradation process of antibiotics are discussed, and the development progress of BDD anode materials is further summarized. At the same time, the combined techniques based on electrocatalytic oxidation on BDD anode are also summarized. Finally, the problems existing in electrocatalytic degradation of antibiotic pollutants with BDD anode and key development direction in the future are further prospected.

Key words: boron doped diamond, electrochemical oxidation, antibiotic pollutants, degradation mechanism, process kinetics
