摘要
将离子色谱技术应用于卷烟纸中无机和有机阴离子同时测定。根据卷烟纸的特殊性，样品采用超纯水超声波草取、滤膜过滤的方法，分析时采用梯度淋洗技术使卷烟纸中的11种阴离子得以很好的分离。该方法具有良好的线性（r=0．9992-0．9998）和精密度（RSD在5．0％以下），回收率在90％～110％之间，检出限在0．003～0．065mg／l之间。该方法操作简单、方便，结果准确、可靠。
Ion Chromatography Technique（IC） was applied to determine the inorganic and organic anions contents in cigarette paper simultaneously. Sample was ultrasonic extracted with high pure water and filtered by filter membrane according to the particularity of cigarette paper. The application of gradient elution technique made a better separation for 11 kinds of anion in cigarette paper. This method had good linear behavior （r-0.9992-0.9998） and precision （RSD〈5.0%）. Recovery rate was 90%-110% and the detection limit was 0.003-0.065mg/l. It was proved that the method is simple and convenient to be operated, and the testing result is precise and reliable.
