| 摘 要： | 在传质理论和质量守恒原理的基础上,建立了超声强化超临界流体萃取(USFE)植物药有效成分的数学模型;确立了用于估算超声强化超临界流体萃取的产物得率的方法;获得了USFE及超临界流体萃取(SFE)过程的体积传质系数和固相内扩散系数。模型与实验结果模拟最大误差小于10%。该模型既证实了超声对SFE有强化效应,又对USFE和SFE过程有很好的预测功能,为工业化提供了理论依据。

| Abstract: | The mathematical model of ultrasonically enhanced supercritical fluid extraction (USFE) of officinal components from plants was constructed based on mass-transfer theory and mass conservation principle.A method to estimate extraction yield by USFE was formed,the volumetric mass-transfer coefficients and the diffusion coefficients in solid phase of USFE process and supercritical fluid extraction(SFE) process were obtained,and the maximum error between the model and experimental result was less than 10%.The model proved the enhanced effect of SFE by ultrasound.It can be used to predict USFE process and SFE process and to provide a theoretical basis for industrialization. |
