Dbd ntp reactor test for degradation of methylene blue

A dbd-ntp reactor was tested for the degradation of 100 ppm methylene blue it was observed that the optimum discharge gap was 35 mm and addition of hydrogenperoxide improved the performance of the reactor, probably due to the formation of hydroxyl radical via fenton reactions.
