臭氧改性对活性炭表面性能的影响及在卷烟中的应用
Effects of ozone modification on surface properties of activated carbon and its application to cigarette filter
摘要
Abstract
The effects of ozone modification on the surface properties, including specific surface area, pore structure, surface function groups and surface acidic group content, of activated carbon (AC) were studied to develop a flavor containing, slow aroma-releasing filter components for cigarette. The effects of ozone-modified AC were investigated by using 2-cyclopentenone as a model molecule. The results showed that: 1) With the prolonged ozone modifying time, the specific surface area, pore volume and surface acidic group content of AC increased. 2) The number of adsorption peaks of chemical bonds between carbon and oxygen in IR spectrum of ozone-modified AC increased, and the type of surface function groups was also increased after modification. 3) After the ozone treatment, the type of adsorption sites of 2-cyclopentenone on AC increased, which increased the desorption activation energy and adsorption capacity. During machine-smoking of test cigarettes containing the treated AC, ozone modification resulted in the increased release of 2-cyclopentenone, while did not significantly affect the release of routine chemical components in mainstream cigarette smoke.关键词
