【 摘 要 】

References(13)Cited-By(6)The decomposition performance of p-chlorophenol in aqueous solution by combination of ultrasound and ultraviolet light was examined. The decomposition of p-chlorophenol in aqueous solution was a pseudo-first-order reaction. The decomposition rate constant increased with increasing ultrasonic intensity and became lower as the initial concentration increased. The p-chlorophenol in aqueous solution was decomposed by OH radicals and photolysis. The synergy effect between ultrasound and ultraviolet light was observed. It was considered that the amount of OH radicals increased due to the photolysis of H2O2, which formed from the sonolysis of water. The decomposition of p-chlorophenol was simply modeled and kinetic analysis was performed. The calculated results were agreed with the experimental data.
