Abstract
A method for decomposing organic compound by spraying water solution into non-equilibrium plasma in gas phase was investigated using a pulsed-corona discharge reactor. The corona reactor used consists of a discharge wire and a cylindrical electrode. Water solution of sodium dedecylbenzensulfonate (C12-LAS) with a concentration of 100mg/L was sprayed into the reactor from a showerhead. The sprayed water solution was circulated into the reactor. C12-LAS was decomposed up to about 90 % by one time exposure in the discharge for the discharging power of 6 W. C12-LAS was mostly decomposed for 30 minutes of a treatment. However by-products were generated by the treatment. It is speculated that the by-product after treating for 300 minutes was CH3(CH2)2-O-(CH2)4-O-(CH2)3CH3.
