卷烟纸中钾、氯和硝酸盐含量的测定

Determination of Potassium, Chlorine, and Nitrate in Cigarette Paper

摘要: 采用连续流动分析法测定了卷烟纸中钾、氯和硝酸盐的含量,其回收率分别为97.5%、90.0%和92.0%,变异系数为2.17%、5.56%和1.46%。并与国家标准规定的方法进行了对比,测定结果与国家标准规定的方法比较一致。同其它方法相比,该方法具有操作简单、测试准确、快速等优点。

Abstract: Potassium, chlorine and nitrate in cigarette paper were determined by continuous flow analytic method. The recoveries of these components were 97.5%, 90.0% and 92.0%, the coefficients of variance were 2.17%, 5.56% and 1.46%, respectively.The results determined by this method were comparable with those obtained by national standard methods of China.This method was simple, fast and accurate.
