离子色谱法同时测定卷烟纸中的有机酸根和无机酸根

Simultaneous Determination of Organic and Inorganic Anions in Cigarette Paper by Ionic Chromatography

  • 摘要: 为了更好地选择与应用卷烟纸,采用超纯水超声萃取-离子色谱法同时测定了8个卷烟纸样品中乳酸根、甲酸根、苹果酸根、酒石酸根、草酸根、柠檬酸根、Cl-、NO2-、NO3-和SO42-含量。结果表明:①这些阴离子的RSD均<7%,回收率在89%~105%;②8个卷烟纸样品中柠檬酸根含量范围为0.2224%~2.2020%,草酸根未检出~0.3215%,苹果酸根0.0010%~0.1620%、乳酸根0.0051%~0.1040%,酒石酸根0.0129%~0.0229%,甲酸根0.0038%~0.0598%,Cl-0.0127%~0.0353%,SO42-0.0062%~0.0292%,NO3-未检出~0.0319%,NO2-0.0001%~0.0052%。该方法适合批量卷烟纸样品中这10种阴离子的快速检测。

     

    Abstract: The contents of lactic, formic, malic, tartaric, oxalic, citric, Cl-, NO2-, NO3- and SO42- 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%, SO42- 0.0062% to 0.0292%, NO-3 n.d.to 0.0319 %, and NO2- 0.0001% to 0.0052%.The method was suitable for the fast simultaneous determination of the said anions in batches of cigarette paper samples.
