Abstract: 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.
