摘要
活化过硫酸盐氧化技术因其自由基持续时间长、pH适用范围广、前体氧化剂稳定等优势,在高级氧化技术的开发和应用中备受关注。本文综述了有效活化过硫酸盐的非均相催化材料(金属氧化物、金属基复合材料、碳材料、天然矿物等),探讨了非均相催化剂的不同催化机制及其催化活性、稳定性、可重复利用性等,并在此基础上提出了非均相催化与其他技术(紫外光辐射、超声、热、微波等)联用以提高其处理效率及范围的发展方向。
Activated persulfate oxidation technology has attracted much attention in the development and application of advanced oxidation technologies,attributing to its advantages of long duration of free radicals,wide application range of pH and good stability of precursor oxidant. In this paper,the heterogeneous catalytic materials (metal oxides,metal matrix composites,carbon materials,natural mineral materials,etc.)for effectively activating persulfate are reviewed. The catalytic mechanism,catalytic activity,stability and reproducibility of the heterogeneous catalysts are discussed. On this basis,the development direction to improve the processing efficiency and processing range by combining heterogeneous catalytic technology with other technologies (with ultraviolet radiation,ultrasound,heat,microwave,etc.)is proposed.
