摘要：
The dependence of equilibrium concentration of 1-propanol from dilute aqueous solutions on mass of sorbent was investigated in order to test the meaning and applicability of the widely used equation for calculation of excess amount of mixture components. On the basis of the experimental data, it was found that the adsorption isotherm was not a single-valued function of the 1-propanol equilibrium concentration. By making use of the exact mass balance of the adsorption system, it was possible to calculate the specific capacity of the sorbent and the absolute composition of the adsorption layer. The partitioning diagram of the system has indicated the strong preferential binding of 1-propanol to the activated carbon applied in our experiments.
