摘要/Abstract

摘要： 为选择性降低卷烟烟气中苯酚的释放量,制备了生物多胺改性石墨烯材料（SP-GO）,利用红外光谱（FTIR）、扫描电镜（SEM）、比表面积检测仪（BET）、动态光散射仪（DLS）等对其进行表征,并将材料添加于卷烟后进行了降苯酚效果考察,探讨了SP-GO对主流烟气中苯酚选择性吸附的作用机理。结果表明,SP-GO具有二维平面结构,其微粒约为2~4层,比表面积为353.9 m²/g;微粒平均粒径为181.3 nm,表面电势值为34.9 mV;分散液的稳定性较好,在28 d内未有较大变化;对卷烟主流烟气中苯酚选择性降低率达到29.2%,单位焦油苯酚降低率可达32.4%;可与苯酚产生强π-π共轭吸附、氢键吸附、电荷吸附等多重吸附,能显著提高其选择性降低卷烟主流烟气中苯酚含量的能力。

Abstract: To selectively reduce the delivery of phenol in mainstream cigarette smoke,a functionalized sorbing material（SP-GO） was prepared via bio-polyamines modification of graphene. The synthesized SP-GO was characterized by fourier transform infrared spectroscopy,scanning electron microscopy,specific surface area analyzer,dynamic light scattering, zeta potential. The effect of SP-GO on the removal of phenol in the mainstream cigarette smoke was investigated,and the selective phenol adsorption mechanism of SP-GO was discussed. The results showed that, SP-GO presented 2-dimensionalflatstrcture composed of 2-4 layers with a specific surface area of 353.9 m²/g. The average particle size of SP-GO was 181.3 nm,the zeta potential of SP-GO was 34.9 mV. The aqueous solution of SP-GO showed good stability in 28 days. SP-GO selectively reduced the phenol in mainstream cigarette smoke by 29.2%%,and the phenol reduction rate to unit of tar in mainstream cigarette smoke reached 32.4%. SP-GO can adsorb phenol specifically via the strong π-π electron conjugated effect between graphene and aromatic rings of phenol,while the amine,hydroxyl and carboxyl groups on the surface of SP-GO can form hydrogen bonds with phenol. Both physical and chemical adsorptions improved the efficiency of selectively phenol reduction in mainstream cigarette smoke with SP-GO.
