Evaluating the Performance of Advanced Oxidation Process by Pyroxene Method for Removal of Reactive Red 198 in Aquatic Environments

Present study oxidation of dyes from dye effluents by O3/H2O2 was investigated. Reactive red 198 (RR198) examined as a target dye. Dye oxidation measured by spectrophotometer. The maximum removal efficiency in optimum conditions including pH=9، contact time=30 minutes، the initial concentration of dye=100 ppm، H2O2 concentration=0. 005 molar، O3 concentration = 0. 04 g/hr were 97. 09% and 87. 56% for synthetic solution and actual wastewater (wastewater from Yazdbaft textile) respectively. O3/H2O2 had good efficiency in dye removal. This method with respect to high efficiency in actual condition could be used in dye removal from various industries. J. Color Sci.
