Degradation of Paracetamol by Fenton-Like Process in Conjunction with Sonication

Abstract:

The degradation of the pharmaceutical paracetamol by using Fenton-like process in conjunction with ultrasonic cavitation was investigated. An evident synergistic effect was found in the combination of sonication and Fenton-like process. Through the application of Response Surface Methodology optimization, the optimum conditions for the degradation of paracetamol were initial pH 3.0, H₂O₂ 7.0 mmol·L^-1 and sponge iron 4 g·L^-1 with acoustic power of 200 W. Under these parameters could obtain 99% degradation of 100mg·L^-1 paracetamol solution within 30 min treatment.
