基于SO_(4)^(-)·的活化过硫酸盐高级氧化法,由于具有经济、高效、环保、安全稳定等优势,近年来其在抗生素的处理方面受到了广泛关注。目前活化过硫酸盐降解抗生素技术主要包括:外加能量活化和外加催化剂活化两大类,此外还有不同活化方式之间融合的耦合技术。外加能量活化的类型主要有热活化、微波活化、超声波活化、光活化、电化学活化和等离子体活化等,其具有工艺过程简单、环保、无二次污染等优点,但却存在能量消耗较大、操作成本较高等劣势。外加催化剂活化主要包括过渡金属活化、炭质材料活化、金属有机框架材料活化等方式,其具有催化活性高、抗生素降解率高等优点,但却存在催化剂稳定性较差、回收使用率低、制备成本较高等缺点。本文分类介绍了各种活化过硫酸盐降解抗生素的过程,追踪了活化过硫酸盐高级氧化法处理抗生素的研究进展,总结了各种活化方式的优缺点,展望了活化过硫酸盐高级氧化法处理抗生素的发展方向,以期为后续的研究者提供方向和指引。

The degradation of antibiotics by advanced oxidation process based on SO_(4)^(-)·has attracted much attention due to its economical, efficient, environmentally friendly, safe and stable advantages.Presently, degradation of antibiotics by activated persulfate(PS) contains external energy and catalyst activation. Besides, the hybrid technologies derived from combination of different methods of activated persulfate have emerged. The single external energy activation for PS are heat, microwave, ultrasound,light, electrode and plasma activation, et al. The external energy activation of PS has simple and green processes without secondary pollution. However, it also has some disadvantages such as high energy consumption and operation cost. The external catalysts for activating PS include transition metals, carbon materials and metal-organic frameworks, et al. The external catalyst activation has advantages of high catalytic activity and high degradation of antibiotics but its disadvantages exist in poor stability, low recovery ratio and high preparation cost of catalyst. The different degradation methods of antibiotics by activated PS are reviewed. Then, the research progress on degradation of antibiotics by activated PS are summarized. The advantages and disadvantages of degradation of antibiotics by activated PS are also given. Finally, the development trends on degradation of antibiotics by activated PS are outlooked. It can provide direction and guidance for subsequent research.
