Abstract

An overview is given of major recent advancements in cold plasma-based water treatment, with specific focus on the degradation mechanisms of organic pollutants. Mechanistic insight is indeed a powerful tool for process optimization considering the treatment duration, its products, and energy costs as it provides guidelines for the design of optimized reactors and the selection of best experimental conditions. The cases considered emphasize the importance of matching the plasma composition in terms of reactive species with the reactivity of the target pollutant(s), and of identifying and understanding the reciprocal effects of different pollutants as well as those of complex aqueous matrices. Harnessing the chemistry activated by the plasma to achieve the desired goal is the key to treatment success. A general strategy is outlined for designing the best plasma experimental set-up and for predicting possible byproducts.
冷等离子体降解水中持久性有机污染物机理研究的重要性
综述了近年来冷等离子体水处理的主要进展,重点介绍了有机污染物的降解机制。考虑到处理时间、产物和能源成本,机械洞察确实是过程优化的有力工具,因为它为优化反应器的设计和最佳实验条件的选择提供了指导。所考虑的案例强调了在反应物质方面使等离子体组成与目标污染物的反应性相匹配的重要性,以及识别和理解不同污染物以及复杂水性基质的相互作用的重要性。利用等离子体激活的化学物质来达到预期的目标是治疗成功的关键。概述了设计最佳等离子体实验装置和预测可能的副产物的一般策略。
