The Research on the Surface Oxidation Modification of Activated Carbon and Its Adsorption Mechanisms of Organic Matter and Heavy Metal Ions

综述了活性炭表面主要的含氧官能团(surface oxygen groups),及表面官能团氧化改性的主要方法。并用Boehm滴定法和FT-IR对活性炭表面含氧官能团进行定量和定性分析。分析了表面含氧官能团对有机物和重金属离子的吸附机理的影响。并对其未来研究前景与方向进行了展望。特别强调了对活性炭作为环境纳米材料(物质)的载体在光催化中开展研究的重要性。

The main types of surface oxygen groups on actived carbon is reviewed, and compared the Boehm titration with FT-IR which are the mostly used to analysis the surface oxygen groups on actived carbon. The adsorption mechanisms on organic functional groups and.heavy metal ions are summaried. Finally, the study of surface oxidation modification of actived carbon is forecasted. The importance of studying the actived carbon as supporter of the nano-materials in the process of photocatalysis is also specially emphasized.
