Description of adsorption equilibria for the systems: Multi-component aqueous solution of organic substances - Active carbon.

Experimental and theoretical investigations of adsorption process for single-, bi-, tri- and tetra-component dilute aqueous solution of organic substances on activated carbon were carried out. Experimental adsorption isotherms from dilute aqueous solutions of benzoic acid, salicylic acid, p-nitrophenol, benzene and their mixtures on activated carbon were measured. The usefulness of theoretical model using the parameters of one-component adsorption fdr prediction of multi-component adsorption was confirmed.
