Product description
- Data on the adsorption of fatty acids on a non-polar carbon adsorbent from aqueous solutions are given in the table:
substance propionic acid butyric acid
С*103, mol/l 0.3 0.5 0.8 0.1 0.2 0.25
G, mol/kg 0.75 1.24 1.98 0.8 1.50 1.86
Assuming that the adsorption isotherm at the indicated concentrations can be described by the approximate form of the Langmuir equation in the region of low concentrations (G = HprKS), show the applicability of the Duclos-Traube rule and calculate the Traube coefficient.
Answer: β = 3.
- How are fatty acid molecules arranged on carbon adsorbents during adsorption from aqueous solutions?
- How will the adsorption of fatty acids from aqueous solutions change if silica gel is used as an adsorbent?
