Adsorption of some nitrogen-containing compounds and benzene derivatives from aqueous solutions on active carbons

摘要

The adsorption from aqueous solutions of benzene derivatives (phenol, benzoic acid, and newly synthesized benzoic acid derivatives containing imidazole heterocycles: hydrazide of 4-(1H-imidazole-1-ylmethyl)benzoic acid and methyl ester of 4-(IH-imidazole-1-ylmethyl)benzoic acid), as well as of imidazole and triazole, on active carbons with various microporous structures is studied. The effect of the nature of adsorbate molecules and the pore sizes of active carbons on the sorption character is analyzed. It is shown that the adsorption from aqueous solutions of the organic derivatives of benzene is determined, on the one hand, by the size of a molecule, and, on the other hand, by its hydration energy.
