2. sparging gas into a dispersion of adsorbent in a solvent
3. mix the liquid element with the dispersion of the adsorbent
Adsorption increases with an increase in the specific surface of the adsorbent, with a decrease in temperature, an increase in pressure, concentration, an increase in the sites of chemical binding of the adsorbent to the element (chemical adsorption). Choosing the best conditions for adsorption you will get the best method.
