Ambient Decontamination by Non -Thermal Plasma in Atmospheric Pressure Air

Abstract

In this research, Cold Plasma, which is non-thermal, is used as a weak gas and ionized , away from equilibrium ;thermally and dynamically. The needle plasma , a discharge in the non-thermal atmosphere is performed by different low-ionizing gases such as argon. The important properties of this plasma are that it works at approximately room temperature .Decontamination of surfaces contaminated and water Of bacteria (Salmonella typhoid, pseudomonas aeruginosa) have been investigated in discharge of atmospheric pressure . The generator cold plasma as non equilibrium . Water treated through the needle pole has led to the removal of biological contamination. The experiments provided to separate different plasma factors, oxidation stress measurements in cell membranes, and induced chemical changes in treated water to better understand plasma factors responsible for disabling microbes. Roots and reactive oxygen species appear to be biologically dominant agents.
