Advanced oxidative processes depend on the production of hydroxyl radicals for the destruction of organic pollutants. The effectiveness of six high ultrasound frequencies and one low ultrasound frequency for the production of hydroxyl radicals was determined by use of the salicylic acid and terephthalic acid dosimeters. Using salicylic acid, the ability of the frequencies to produce hydroxyl radicals in the presence of the oxidant hydrogen peroxide was assessed. Additionally, the use of selected ultrasonic frequencies was studied in combination with hydrogen peroxide for the degradation of the model pollutant, acid orange 7 in the presence of iron powder or activated carbon cloth.
Raw data was collected from analytical equipment (high performance liquid chromatography, fluorimetry, spectrophotometry) for laboratory experiments using ultrasound apparatus, with and without hydrogen peroxide, iron powder and activated carbon cloth.
