摘要
为了降低卷烟主流烟气中酚类有害成分,以乙醇、环己醇、聚乙二醇400和聚乙二醇600不同醇类为原料与草酸亚铁反应制备了不同碳空心材料,利用傅里叶变换红外光谱(FTIR)、扫描电子显微镜(SEM)、比表面及孔径分析仪对其进行了表征,并分别考察了添加不同碳空心材料的复合滤嘴对卷烟主流烟气中酚类有害成分释放量的影响。结果表明,碳空心材料具有优异的吸附性能,其对主流烟气中邻苯二酚、间苯二酚、对苯二酚、苯酚、邻甲酚、间甲酚和对甲酚酚类有害成分有良好的吸附能力。尤其乙醇制备的碳空心材料吸附酚类有害成分的能力最高,其吸附能力比活性炭材料高,对主流烟气中主要酚类有害成分吸附率达到50%以上,能够明显降低主流烟气中酚类有害成分。
In order to reduce harmful phenolic ingredients in the mainstream smoke, different carbon hollow materials were synthesized through ferrous oxalate with ethanol, cyclohexanol, polyethylene glycol 400 and polyethylene glycol 600, respectively. These different carbon hollow materials were characterized via Fourier Transform Infrared Spectroscopy（FTIR）, Scanning Electron Microscopy（SEM） and BET specific surface area analyzer. These materials were applied in composite filter for testing the removal efficiency for phenolic compounds. The results showed that these carbon hollow materials had excellent adsorption capability for catechol, resorcinol, hydroquinone, phenol, o-cresol, m-cresol and cresol phenolic harmful ingredients in the mainstream smoke. The adsorption capability of carbon hollow material prepared from ethanol was much higher than those of other samples and activated carbon material. The adsorption efficiency of carbon hollow material prepared from ethanol was more than 50% for phenolic harmful ingredients and it could significantly reduce the phenolic harmful ingredients in the mainstream smoke.
