Bactericidal effects and formation of ROS/RNS in water sprayed through cold air plasma
Original language description
Bio-decontamination and chemical effects induced by plasma in water upon electro-spraying through cold atmospheric pressure plasma of DC-driven positive transient spark discharge in air were investigated. Inactivation of Escherichia coli in plasma treated water was determined in dependence on the solution pH (controlled by buffers) and correlated with chemical changes induced in water. Productions of H2O2, nitrites, nitrates, peroxynitrites and pH changes were determined. The degree of inactivation andoxidative damage of bacteria increased with increasing acidity of the solution. Acidified nitrites interacting with H2O2 were determined as the most important bactericidal ROS/RNS agents in water treated by air plasma.
