Abstract

Summary form only given. Non-thermal plasma generated at atmospheric pressure produces a complex effect caused by reactive molecules, charges, electric fields, and ultraviolet radiation. The role of these components has been studied, and it was noticed, that inactivation efficiency highly depends on presence of charged species for room air conditions, but radiation effect in air plasma is almost always negligible. To study the role of plasma-produced charged particles, we have used DC corona discharge, where stable and uniform generation of various neutral active species and ions is possible.
