摘要: This paper presents a study on the effect of ultrasonic frequency both nucleation and degradation paracetamol under sonication. The irradiation was investigated for frequencies ranging from 41 to 1140 kHz. results obtained in this show that lower are preferable, enhance rate limit degradation. A reduction metastable zone width observed all experiments when applying ultrasound. highest achieved at kHz decrease with increasing frequencies. Degradation limited kHz, while significantly higher levels Radical formation seems be main mechanism
