摘要： 采用氧化酰化法,通过共价键合反应在活性炭表面键合接枝了邻氨基、间氨基和对氨基3种氨基吡啶分子。借助FT-IR、XPS、元素分析和氮气吸附研究了活性炭键合改性前后表面化学与孔径结构的变化规律,考察了接枝分子结构差异与活性炭的反应效能。结果表明间氨基吡啶分子在活性炭表面键合效率最高,表面N/C值达到0.10,样品氮元素摩尔分数达到7.74 %。这表明接枝分子电子效应的差异影响接枝键合的效率,为以酰胺键进行高效接枝改性活性炭提供了科学依据。

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
