Vermiculite containing 5% zirconium was used as a catalyst. The destruction processes of 2,4-DCP proceed efficiently, the degree of decomposition increases in the combined plasma-catalytic process by a factor of 1.33 and reaches 80%. The experimental results were processed according to the first-order kinetic law (R2 > 0.97), according to which the effective constants (0.36 ¡À 0.04) and (0.51 ¡À 0.03) s-1 and the decomposition rates of 2,4-DCP (106 and 123 ¦Ìmol/l¡¤s) when treating model solutions without a catalyst and with vermiculite + Zr 5%, respectively, and the energy costs are 0.012 and 0.017 molecules/100eV. The main decomposition products present in the solution have been determined to be carboxylic acids, aldehydes, the contribution of which does not exceed 2%, as well as chloride ions, and in the gas phase they are carbon dioxide and molecular chlorine (the share of which does not exceed 1.5% of total chlorine content in the system). %K 2 %K 4-Dichlorophenol %K Dielectric Barrier Discharge %K Plasma %K Oxygen %K Treatment %K Water Treatment %K Catalyst %K Zirconium %K Vermiculite %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=128174
