Application of SCR technology for degradation of reactive yellow dye in aqueous solution

Abstract

The effect of sonochemical reactors (SCR) technology upon the degradation of reactive yellow dye has been studied and reported here. Sonochemical reactors (ultrasound irradiation) produce strong cavitation in aqueous solution causing shock wave and reactive free radicals by the violent collapse of the cavitation bubble. These effects should contribute to destruction as well as the decomposition of dyes. This research investigated the efficacy of sonochemical reactors for decolourizing reactive yellow dyes in aqueous solution. In this research, the influence of concentration, frequency, treatment time, and reactor power on the dye decomposition were investigated. The results obtained from the study carried out have shown that SCR can be used effectively for degradation of reactive yellow dyes. The results suggested sonochemical reactors provided maximum destruction, and 120 min treatment time at 130 kHz and 500 W were the most effective for the maximum degradation of reactive yellow dye. © 2008, CAWQ.
