Original Abstract

Electrical discharges interacting with liquids are one of the hot topics of current plasma physics and plasma chemistry. A special tension is kept for the discharges generated directly in liquid phase or in bubbles in the liquid phase. Mainly various water solutions are studied. The presented results are connected mainly to the diaphragm discharge configuration and the newly designed electrode system based on this configuration. The electric discharge in liquid phase generated both physical and chemical effects. The emission of UV (and partially also VUV) radiation and shock waves are the main physical effects. Chemical effects are related mainly to production of OH radicals (fast recombining to stable hydrogen peroxide) and atomic hydrogen and oxygen species in case of water solutions without additional bubbling. The main studied applications are in waste and drinking water treatment (like decomposition of phenol, dyes, hormones, pharmaceutics, etc.), surface treatment, and nanoparticles synthesis. A special focus is given to biomedical applications like sterilization, wound healing, ablation, etc. The applications in water treatment and surface treatment of ancient glass base on our own research will be presented in details.
