摘　　要：为确定烟用接装纸中二氧化钛的含量,建立了湿法消解-电感耦合等离子体质谱法（ICP-MS）测定烟用接装纸中二氧化钛的方法。结果表明,在0.1-200μg/L（以Ti计,下同）范围内,标准工作曲线的相关系数为1;加标回收率90.95%-101.66%;日内重复性变异系数低于1%,日间重复性变异系数低于5%;仪器检出限为0.02475μg/L,方法检出限为0.716μg/L,定量限为2.388μg/L。该方法具有检出限低,准确度高,精密度好,简便快速的特点,可以用于烟用接装纸样品中二氧化钛含量的快速测定。Method of determining the content of titanium dioxide in tipping paper by wet digestion ICP-MS was established. Theresults indicated that the correlation coefficient of the standard working curve was 1 within the concentration 0.1-200μg/L, therecovery rate was from 90.95% to 101.66%, RSD of intra-day repeatability was less than 1%, and RSD of inter-day repeatability wasless than 5%. The instrumental detection limit and the methodological detection limit were 0.02475 μg/L and 0.716 μg/L,respectively, and the quantitation limit was 2.388 μg/L. This method has the advantage of low detection limit, high accuracy, fineprecision with simplicity and rapidity. It is effective to determine the content of titanium dioxide in tipping paper.
