Abstract
In this work, Basic violet 10 (BV10) sonolysis has been characterized. The experiments have been conducted using an ultrasonic reactor operating at 300 kHz and 60 W. The degradation of the dye during the sonolytic reaction was assessed by absorption abatements at two bands: the visible, which is responsible for the chromophoric compound, and at UV-254, which represents the absorption of aromatic rings in the dye. The obtained results indicate that the rate of the color decay was not first order kinetic as generally reported in the literature. The destruction of the aromatic ring in the dye was slower than that of color, signifying the priority of hydroxyl radical attack on the chromophoric group of the dye. It was also found that the BV10 removal efficiency decreased with increasing initial dye concentration while, initial degradation rate of the dye increased in a non-linear manner with the increase in the initial BV10 concentration.
