Degradation of XXXX by in-situ electrochemically generated oxidant.

@entity16647 @entity273 @entity26 @entity9049
A novel in-situ electrochemical oxidation method was applied to the degradation of wastewater containing @entity16647 . Under @entity26 sparging, the strong oxidant, @entity9049 , could be in-situ generated through the reduction of @entity26 on the surface of the cathode. The removal rate of @entity16647 could be increased 149% when @entity26 was induced in the electrochemical cell. The promotion factor was estimated to be about 82.63% according to the pseudo-first-order reaction rate constant (min(-1)). Important operating parameters such as current density, sparged @entity26 rate investigated. Higher sparged @entity26 rate could improve the degradation of @entity16647 . To make full use of @entity26 , however, sparged @entity26 rate of 0.05 m(3)/h was adopted in this work. Oxidation-reduction potential could remarkably affect the generation of @entity273 . It was found that the removal rate of @entity16647 was not in direct proportion to the applied current density. The optimum current density was 3.5 mA/cm(2) when initial @entity16647 concentration was 100 mg/L and sparged @entity26 rate was 0.05 m(3)/h.
