The dependence of the equilibrium concentration of dilute aqueous solutions of 1-propanol and 2-propanol on the mass of adsorbent for two types of activated carbon was investigated at fixed initial concentrations. Two kinds of differential equation were proposed for the characterization of these curves. The solution functions of the given differential equations were fitted to the experimental data. The second model was accepted as providing a good description of the required functional relationship. The similarity and differences in the values of the constants relative to the functions arising from the accepted model were also discussed for the two types of activated carbons.
