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

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SO4^2-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％，SO4^2-0．0062％～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。

The contents of lactic, formic, malic, tartaric, oxalic, citric, CL^- , NO2^- , NO3^- and SO4^2- 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% 0.0052%. The cigarette paper method was samples. , SO4^2- 0.0062% to 0.0292%, NO3^- n.d. to 0.0319 %, and NO2^- 0.0001% to suitable for the fast simultaneous determination of the said anions in batches of cigarette paper samples.
