GC-MS and Spectrophotometric Analysis of Degradation of Commercial Textile Dye Reactive Black CNN by Advance Oxidation Processes
Spectrophotometric Analysis of Textile Dye
This study evaluates the efficiency of Fenton processes which are one of advance oxidation processes for degradation of reactive black CNN from aqueous dye solution. Samples were treated with Fenton's, photo and Fenton's like reagent to check and compare % decolourization efficiency of the pro- cesses. Optimization of different operating parameters like dose of dye, concentration of H2O2, concentration of iron salts, contact time and temperature has been determined. Results showed that the overall degradation of Reactive Black CNN was much faster by photo Fenton oxidation process as compare to Fenton or photo Fenton like oxidation. For the three oxidation systems, the percentage color removal efficiency depends on [Dye], [Fe2+], [Fe3+], [H2O2], temperature, contact time and sun light exposure time.
