Assessment of effectiveness of reduction in the potential toxicity of water after plasma treatment

Abstract
Physical and chemical processes of decomposition of some "criterion" contaminants of surface and wastewaters (phenol and some synthetic surfactants) in plasma systems have been studied. The decomposition degrees of examined compounds were from 75 to 99 % depending on the processing conditions. Intermediate materials are shown to be carboxylic acids, aldehydes, sulfate-ions, and nitrate-ions. Carbon dioxide was the finite product of decomposition of aldehydes and carboxylic acids. Based on experimentally measured concentrations of phenol, sulfonol, and sodium laurilsulfate decomposition products, the potential toxicity of initial solutions and the solutions after plasma effect for the purpose of determination of effectiveness of its decrease has been calculated. The results with the data obtained by biotesting method are compared.
