Comparison of Organic Dyes Decomposition by DC Diaphragm Discharge, Electrolysis and UV Radiation Effects

Paper in proceedings (conference paper)

Influence of electrolytic decomposition of selected organic dyes by the DC diaphragm discharge was confirmed by the study in water solutions of various electrolytes. Influence of electrolyte kind, its concentration (providing different solution conductivity) as well as influence of input current magnitude on the dye removal was investigated. Dye concentration was determined by the absorption spectroscopy. Dye removal dependence on input current was directly proportional with an almost linear tendency. Also increasing solution conductivity enhanced dye decoloration. On the other hand, electrolyte kind did not show any significant effect on the dye decomposition.
