Abstract

Surface modification of cellulose acetate filter rods with low temperature plasma was performed to explore the retention and adsorption effect of modified filter rods on typical components (CO, HO, benzene, and formaldehyde) in cigarette smoke. The surface structure and composition of the cellulose acetate filter rods were modified by changing the plasma treatment time. The modified filter rods were characterized by N physical adsorption (BET), scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), contact angle of HO, Fourier transform infrared spectroscopy (FTIR) and DRIFTS. Various functional groups were found on the surface of filter rods with the introduction of plasma modification, which exhibited strong retention performance for water vapor in cigarette smoke at room temperature and significantly enhanced adsorption for harmful substances (CO, benzene, and formaldehyde) in cigarette smoke.

摘要

采用低温等离子体对醋酸纤维素滤棒进行表面改性,以探究改性滤棒对卷烟烟气中典型成分(一氧化碳、水、苯和甲醛)的截留和吸附效果。通过改变等离子体处理时间对醋酸纤维素滤棒的表面结构和组成进行改性。采用氮气物理吸附(BET)、扫描电子显微镜(SEM)、X射线衍射(XRD)、X射线光电子能谱(XPS)、水接触角、傅里叶变换红外光谱(FTIR)和漫反射红外傅里叶变换光谱(DRIFTS)对改性滤棒进行表征。随着等离子体改性的引入,在滤棒表面发现了各种官能团,其在室温下对卷烟烟气中的水蒸气表现出较强的截留性能,并显著增强了对卷烟烟气中有害物质(一氧化碳、苯和甲醛)的吸附。
