Abstract

Abstract: Three kinds of pyridine molecules were grafted by covalent bonds onto activated carbons using the processes of oxidative and acylation. Regularity for the changes of the surface physicochemical properties and pore structure before and after modification were studied by the measurement technologies such as FT-IR,XPS,elemental analysis and N₂ adsorption. The structural differences of grafting molecules and the reaction performance of activated carbon were investigated. The results showed 3-aminopyridine has the highest grafting efficiency. It was determined that the surface N/C value of activated carbon was 0.10 and the nitrogen content was up to 7.74%. The results showed that the difference of the electron effect of the grafted molecules affected the grafting efficiency. This provided a scientific basis for highly efficiently grafting by acylation on activated carbon.

Key words: activated carbon, covalent grafting, aminopyridine, oxidation, cylation
