摘要
从热力学和动力学两方面介绍了近年来超声波应用于吸附/脱附过程的研究结果。比较了非超声波/超声波作用下吸附等温线的变化,分析了超声波强度、频率、第三组分的加入等因素对吸附/脱附相平衡影响;以及非超声波/超声波作用下吸附/脱附动力学的变化,并对温度、超声功率、初始浓度和颗粒大小等因素对吸附/脱附速率的影响及其原因进行分析。
The recent research on ultrasound application to adsorption/desorption process is presented. The adsorption isotherms at the absence and presence of ultrasound are compared. Several factors, which affect adsorption and desorption phase equilibrium, are analyzed, including ultrasonic intensity, frequency and the addition of a third components. The adsorption/desorption kinetics at the absence and presence of ultrasound is also compared. Several factors, which affect adsorption/desorption rate, and the causes are analyzed, including ultrasonic power, temperature, original concentration and adsorbent size.
