DECOLOURIZATION OF WASTEWATER FROM THE PRODUCTION AND APPLICATION OF ACID BLUE 62
Original language description
The aim of this work was to evaluate the possibility of bleaching effluents containing aminoanthraquinone dyes Acid Blue 62 selected by indirect electrochemical oxidation of single-chamber laboratory electrolysers. To evaluate the effectiveness of model solution decolorized wastewater containing Acid Blue 62, UV-VIS spectroscopy was chosen as a suitable method. During electrochemical oxidation velocity changes were measured in model bleach solutions depending on the amount of supporting electrolyte, which was sodium chloride. Furthermore, decolourization rate was observed depending on the voltage of electrodes, which remained constant during the measurement. The sampleswere taken at various time intervals corresponding to chromaticity change of the electrolyzed solution. For the analysis of samples, (TOC, CODCr, AOX) and GC-MS (gas chromatography with mass spectrometer assigned) and liquid chromatography were used as auxiliary methods. The results of GC-MS established reaction mechanism of Acid Blue 62.
