摘要
Results obtained using a bipolar pulsed DBD reactor for Indigo Carmine (IC) water treatment are reported in this investigation. Effects of such parameters as gas flow rate, solution conductivity, pulse repetitive rate and ect., on color removal efficiency of IC solution were studied. The results showed that color removal efficiency was greatly enhanced by bubbling air into the reactor. Decolorization efficiency of the reactor increased with the increase of the pulse repetitive rate, decreased with the increase of the initial solution conductivity and gap distance. In addition, concentrations of ozone in the effluent gases and hydroxyl peroxide in the aqueous phase were determined and their functions on the decolorization were analyzed.
