Özet

In this study, the adsorption of 2-, 3-, 4-anisidines on metal (Co)-supported pumice has been performed. The amount of cobalt on pumice was measured by ICP-OES analysis. Scanning electron microscopy indicated the formation of metal modification on the pumice surface. The samples were examined by Fourier transform infrared spectroscopic analysis of the adsorption process. The data show that after cobalt cation was supported on pumice, the adsorption of 2-, 3-, 4-anisidines was characterized by the bands at 2,958, 1,633, 1,450, 760, and 734 cm(-1). Adsorption of anisidines was observed only on Co-supported pumice, not on bulk pumice. The results show that the main adsorption process can only occur on the metal cation and metal oxide surface of pumice. Geometrical effects of isomers were monitored after adsorption.
