Sonocatalytic performance of AgBr in the degradation of organic dyes in aqueous solution

• AgBr can be used in sonocatalytic degradation of dyes.
• The structure and properties of AgBr was discussed in detail.
• The kinetic model and its parameters were also discussed in detail.

AgBr sonocatalysts were prepared by a simple method. The AgBr sonocatalysts exhibited excellent sonocatalytic activities against the decolorization of methylene blue, rhodamine B, and methyl orange. By determining the content of OH radicals in the ultrasonic degradation of organic dyes, many OH radicals were detected, which may be responsible for the high sonodegradation rate over AgBr under ultrasonic radiation. Based on the effects of the initial dye concentration on the sonodegradation, we also discussed and analyzed the kinetic data, and the results are consistent with the first-order kinetic rate equation.
