摘　　要：把不同碘值、pH值及水洗过的活性炭添加到复合嘴棒中,考察了它们对焦油和一氧化碳的吸附能力,发现未水洗,碱性pH值,高碘值的活性炭可以产生较好的吸附效果。但在卷烟开发中,为了避免卷烟香气浓度的减少,适合选择中等碘值弱碱性的活性炭。　Effect of iodine and pH value of activated carbon from complex filter on the absorption of tar and carbon monoxide was studied.Result showed that unwashed activated carbon with alkaline pH and high iodine value had good adsorption of tar and carbon monoxide.However,activated carbon with medium iodine value was chosen to avoid the decrease of tobacco fragrance.
