摘要
[目的]测定卷烟纸样品中6种阴离子含量。[方法]以超纯水为萃取剂、IonPac AS19阴离子交换柱为分离柱，采用离子色谱法进行梯度洗脱来测定卷烟纸样品中的乳酸根、乙酸根、甲酸根、氯离子、磷酸根和柠檬酸根的含量。[结果]试验实现了5种卷烟纸样品中乳酸根、乙酸根、甲酸根、氯离子、磷酸根和柠檬酸根的定量分析，且6种阴离子的回收率均在91.0%~109.5%，相对标准偏差在0.82%~6.26%。[结论]该方法准确、简单、可靠，适用于卷烟纸样品中相关组分的测定。
Abstract
[Objective] To detect the contents of six anions in cigarette paper. [Method] With ultrapure water as the extraction agent,six anions in cigarette paper were detected by ion chromatography on IonPac AS19 column. Gradient elution was carried out. [Result] Six anions in five cig-arette paper samples were quantitatively analyzed,which were lactate,acetate,formate,chloridion,phosphate and citrate. The recovery rates of six anions were between 91. 0% and 109. 5%;and their relative standard deviations ranged from 0. 82% to 6. 26%. [Conclusion] This method is ac-curate,simple,reliable and suitable to determinate the relative components in cigarette paper.
