12. The following experimental data were obtained on the adsorption of acetic acid on charcoal from 200 ml of aqueous solutions of acetic acid.
Solution concentration
acetic acid before Co adsorption, mol/l 0.503 0.252 0.126 0.0628 0.0314 0.0157
Concentration of acetic acid solutions after adsorption Comp, mol/l 0.434 0.202 0.0899 0.0348 0.0113 0.0033
Mass of adsorbent (coal) m, g 3.96 3.94 4.00 4.12 4.04 4.00
Prove that these data describe the Freundlich adsorption isotherm: A = K Comp1/n, where A is the number of grams of adsorbed acid. Estimate the equation constants K and n.
