中文摘要:
      为探讨Zn(NO3)2改性多孔炭的制备以及其对液蜡油中芳烃的吸附研究,本文以三聚氰胺为氮源,柠檬酸钙为碳源,硝酸锌为造孔剂,制备了多孔炭材料.利用氮气吸附/脱附、X射线衍射(XRD)、傅里叶变换红外光谱(FT-IR)、扫描电子显微镜(SEM)、拉曼光谱等对产物的形貌和结构进行了表征,并探究了多孔炭对液蜡油中芳烃的吸附行为. 结果表明:硝酸锌改性的多孔炭材料具有更高的比表面积(827.5 m2.g-1)并对液蜡油中的芳烃具有更好的吸附性能(吸附量qe高达32.45 mg.g-1),远高于商业活性炭、硅胶和10X分子筛.
英文摘要:
      In order to investigate the preparation of Zn(NO3)2 modified porous carbon and its adsorption on aromatic hydrocarbons in liquid wax oil, the porous carbon material was prepared by using melamine as nitrogen source, calcium citrate as carbon source and zinc nitrate as pore-forming agent. The morphology and structure of the carbon materials were studied by N2 adsorption/desorption, X-ray diffraction (XRD) , FourierStransformSinfraredSspectroscopy( FT-IR), scanning electron microscopy (SEM) and Raman spectra. The adsorption behavior of aromatic hydrocarbon in the liquid wax was investigated. The results showed that the zinc nitrate modified porous carbon has a higher specific surface area(827.5 m2.g-1)and better adsorption performance (adsorptionScapacity qe can reach up to 32.45 mg.g-1), which was much higher than commercial activated carbon, silica gel and 10X molecular sieve.
