摘　　要：采用有机溶剂溶解复合滤棒中二醋酸纤维素丝束,经过滤分离、干燥后,测出复合滤棒中活性炭的施加量,研究了丙酮、四氢呋喃、二氯甲烷溶剂和不同萃取温度对测定结果的影响.确立了以丙酮为溶剂的测试方法,该方法试验回收率为98.3%～100.6%,相对标准偏差(RSD)在1.5%～2.8%之间.该方法用于测定复合滤棒中活性炭的施加量,结果令人满意.Organic solvent was used to solve diacetate cellulose tow in composite filter rod. After filter and dry processing, the exerting quality of activated charcoal in composite filter rod was determined. The effects on acetone, etrahydrofuran, methylene chloride and different extracting temperature on the testing results were investigated. The testing method using acetone as solvent was established, with which the relative standard deviation （RSD） ranges from 1.5% to 2.8% and the recovery rate from 98.3% to100.6%.
