Study on degradation of phenol in aqueous solution by ultrasound technology

The degradation effect of phenol and influence of affecting factors such as initial concentration,reaction temperature,pH are studied in this paper.Results show that: under the conditions of aqueous solution 200mL,phenol initial concentration 135.15 mg/L,reaction temperature 30℃,initial pH value of 3.0,ultrasonic irritation for 4 hours,the degradation of phenol reaches 5.64%.In addition,aeration and H2O2 could accelerate the phenol removal rate,and the addition of Fenton reagent can raise the degrading-rate to 61.60%.
