| Research Abstract |
In the present study, to establish the high efficient supercritical carbon dioxide extraction process, the effect of ultrasonication on supercritical carbon dioxide extraction process was investigated using the ultrasound-assisted extraction apparatus that we had designed and developed. All experiments were carried out at the ultrasonic frequencies determined from respective frequency-transducer impedance curves which were obtained under different pressure and temperature conditions. The results demonstrated that the extraction rate in ultrasound-assisted process was faster compared with that without ultrasonication.
