活性炭对香烟烟雾中有害微量元素的吸附效果

The Adsorptive Effect of Activated Carbon to Hazardous Trace Elements in Cigarette Smoke

为提高过滤嘴对香烟烟雾中有害成分的吸附能力，研究了活性炭过滤嘴和醋酸纤维过滤嘴对香烟烟雾中镉（Ｃｄ）、镍（Ｎｉ）和砷（Ａｓ）的吸附效果。结果表明活性炭过滤嘴对Ｃｄ、Ｎｉ和Ａｓ的吸附能力分别为醋酸纤维的４．２５、３．５８和１．６１倍。建议在香烟过滤嘴的加工生产中添加适量活性炭，以增强对有害成分的吸附。

To advance the adsorptive capacity of cigarette filter to hazardous composition in cigarette smoke,a study on the adsorptive effect of activatedcarbonmade filter and celluloseacetatemade filter to cadmium,nickel and arsenic in cigarette smoke was carried outThe results showed that the adsorptive capactity of activated carbon to cadmium,nickel and arsenic were 425,358 and 161 times as large as those of celluloseacetatemade filterIt was suggested that moderate amount of activated carbon should be added into cigarette filter during its production process to advance the adsorptive effect to hazardous composition
