Abstract

Pesticides are being discharged into the environment at an increasing rate, particularly into water resources, as agricultural productivity increases. These contaminants need to break down and mineralize as soon as possible since they are extremely dangerous to aquatic life and human health. The advanced oxidation method based on sulfate radicals (SR-AOP) has gained popularity recently for treating organic pollutants like pesticides because of its great efficacy and low environmental impact. This article goes into detail about the many ways for activating persulfate (PS) and peroxymonosulfate (PMS) for pesticides degradation, such as UV light, carbon-based materials, TMs, ultrasonic, electrochemical, heat, microwave, photoelectrons, alkali, and hybrid activation. The mechanisms of pesticide the degradation by SR-AOP, as well as the detection of reactive oxygen species (ROS), are also addressed. The effect of operational parameters such as PS/PMS concentration, catalyst dose, pH, pesticide starting concentration, and organic and inorganic matter on pesticide degradation by SR-AOP is also discussed. The toxicity of the degraded intermediates, as well as enhancing pesticide total mineralization under SR-AOP, was also investigated. Finally, prospects for future research and application of SR-AOP in pesticides removal from water are highlighted.

基于硫酸根的高级氧化技术去除水中的农药 最新技术综述
随着农业生产力的提高,农药排放到环境中的速度越来越快,尤其是排放到水资源中。这些污染物需要尽快分解和矿化,因为它们对水生生物和人类健康危害极大。基于硫酸根自由基的高级氧化法(SR-AOP)因其高效且对环境影响小,最近在处理农药等有机污染物方面越来越受欢迎。本文详细介绍了活化过硫酸盐(PS)和过硫酸盐(PMS)降解农药的多种方法,如紫外光、碳基材料、TMs、超声波、电化学、热、微波、光电子、碱和混合活化等。此外,还探讨了 SR-AOP 降解农药的机理以及活性氧(ROS)的检测。此外,还讨论了 PS/PMS 浓度、催化剂剂量、pH 值、农药起始浓度以及有机物和无机物等操作参数对 SR-AOP 降解农药的影响。此外,还研究了降解中间产物的毒性,以及在 SR-AOP 条件下提高农药总矿化度的问题。最后,强调了 SR-AOP 在去除水中农药方面的未来研究和应用前景。 图文摘要

期刊介绍: International Journal of Environmental Research is a multidisciplinary journal concerned with all aspects of environment. In pursuit of these, environmentalist disciplines are invited to contribute their knowledge and experience. International Journal of Environmental Research publishes original research papers, research notes and reviews across the broad field of environment. These include but are not limited to environmental science, environmental engineering, environmental management and planning and environmental design, urban and regional landscape design and natural disaster management. Thus high quality research papers or reviews dealing with any aspect of environment are welcomed. Papers may be theoretical, interpretative or experimental.
