Water solutions of organic dye Direct Red 79 were treated by DC high voltage created by diaphragm discharge (input power up to 160W). Higher dye decoloration (60% after 40min) was observed in the anode part of the reactor by UV–VIS spectroscopy. Recorded absorption spectra showed shifts of absorption maximum to lower wavelength values that were related to the formation of stable degradation products...
The process of organic dye removal from various water solutions containing organic dyes and inorganic additives by DC diaphragm discharge has been studied in he so-called “negative part” of this discharge. The concentration of treated dye decreased almost exponentially to constant residual value. The final dye concentration reached approximately 20% of the initial value after 10 min of treating a...
