Abstract:
The contents of lactic, formic, malic, tartaric, oxalic, citric, Cl
-, NO
2-, NO
3- and SO
42- anions in eight cigarette paper samples were determined.The samples were extracted with super purified water under ultrasonic and determined by ionic chromatography.The results showed that: 1) the recoveries of the said anions ranged from 89% to 105% with RSDs of below 7%;2) the content ranges of anions in the samples were: citric from 0.2224% to 2.2020%, oxalic n.d.(not detectable) to 0.3215%, malic 0.0010% to 0.1620%, lactic 0.0051% to 0.1040%, tartaric 0.0129% to 0.0229%, formic 0.0038% to 0.0598%, Cl
-0.0127% to 0.0353%, SO
42- 0.0062% to 0.0292%, NO-3 n.d.to 0.0319 %, and NO
2- 0.0001% to 0.0052%.The method was suitable for the fast simultaneous determination of the said anions in batches of cigarette paper samples.
