大气压冷等离子体处理水溶液:液相活性粒子检测方法综述

In recent years, cold atmospheric-pressure plasma has attracted considerable attention due to its great potential in diverse application fields such as biomedicine, material processing, and environmental protection. More and more investigation results show that the plasma-generated reactive species play a key role in these applications. Besides, it is found that targets to be treated by plasmas are always covered by a liquid layer or even immersed in liquids, making the interaction between plasma and liquid inevitable. The gaseous reactive species in cold plasma need to be converted into aqueous ones before they act on the targets. There are many kinds of aqueous reactive species generated by cold atmospheric-pressure plasma, but the cognitive level of plasma-liquid interaction and the development of related applications have been restricted by the lack of methods, poor specificity, and difficulty in quantification of the detection technology. In this paper, the detection methods for eleven kinds of reactive species in plasma-activated water solutions, including reactive oxygen species, reactive nitrogen species and hydrogen species, are summarized and introduced in detail, which can provide a reference for related theoretical and application researches.
