Organic Dye Decomposition by DC Diaphragm Discharge in Water: Effect of Solution Properties on Dye Removal

Original language description

The process of organic dye removal from various water solutions containing organic dyes and inorganic additives by the DC diaphragm discharge has been studied in 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 minutes of the treatment of the Direct Red 79 dye solution. The dye de-coloration was also affected by the dye structure. The azo and diazo compounds have been degraded significantly faster to be compared to thiazine compounds. The degradation process required an optimal adjustment of the initial solution conductivity. The optimum conductivity of approximately 600 microS cm-1was found when the solution contained either NaCl or NaBr electrolytes. The type of electrolyte used for the conductivity adjustment considerably affects the process of dye de-coloration. Halogen compounds have been found the most proper
