Optimizing Organic Dye Degradation in a Low Power Atmospheric Pressure Plasma Discharge
Abstract
Plasma-based water treatment has emerged as one of the most effective advanced oxidation processes. One of the major issues inhibiting the development of plasma-based water treatment is attributed to large energy consumption. In order to optimize organic contaminant removal, the production of oxidizing radicals in the gas phase and their effective delivery to the water need to be maximized. This study demonstrates the degradation of an industrial dye, indigo carmine, dissolved in water using a nanosecond pulsed dielectric barrier discharge in a custom reactor. The degradation rate of the indigo carmine is dependent on various operating parameters, such as the applied voltage, gas flow, and gas mixture. The rate of degradation can be increased by applying higher voltages and introducing a small amount of air with helium.
