The 20 kHz ultrasound-induced degradation of non-steroidal, anti-inflammatory drug diclofenac (DCF) was investigated. Several operating conditions, such as power density (25-100 W/L), substrate concentration (2.5-80 mg/L), initial solution pH (3.5-11), liquid bulk temperature and the type of sparging gas (air, oxygen, argon), were tested concerning their effect on DCF degradation (as assessed measuring absorbance at… Continue reading Ultrasonic degradation, mineralization and detoxification of diclofenac in water: Optimization of operating parameters
