Sažetak
The effect of the acidity of the media on the adsorption of phenol and cresols was investigated using TLC and using the Rf-values as a measure of the adsorption ability of active carbon. Three types of chromatographic layers were employed: silica gel, silica gel cointaining 3% of active carbon and silica gel cointaining 6% of active carbon. Standard solutions of phenol, m-cresol and o-cresol were used as the samples. The acidic acid content of the solvent mixture significantly influences the adsorption of phenol and cresols on the active carbon layer. An increase in the acetic acid content results in a decrease of the adsorption of phenols. However, under specific conditions [81:5:7 hexane-diethyl ether-acetic acid, and 48:2:8 benzene-acetone-acetic acid developers] the competitive adsorption of phenols and acetic acid may take palce, which has been observed by a steep increase in the adsorption of phenol and cresols.
