Keywords:plasma-liquid interactions

Plasma–liquid interactions are important in many applications ranging from environmental remediation to material science and health care. Different types of non-equilibrium electrical discharge plasmas generated either directly in the liquid, in the gas phase over or in contact with a liquid have been shown to generate a number of physical and chemical processes. Oxidative properties of reactive oxygen species and nitrogen species are generally accepted to play central role in the chemical and biological effects of plasma produced in gas-liquid environments. These species can react at or penetrate through the plasma-gas/liquid interface and dissolve into the bulk liquid, and can also initiate secondary chemical processes in the liquid. In addition to the use for chemical decontamination processes, plasma in liquid can be used for material processing and synthesis. In this talk an overview of basic principles of electrical discharge plasmas in liquids will be presented with particular emphasis on elementary physical and chemical processes induced by non-equilibrium plasma in aqueous liquids and their applications.
