| 中文摘要: |
| 快速分析卷烟纸中钾（K）和钠（Na）元素含量对于卷烟纸生产的工艺控制起着重要的作用，本课题探讨了一种采用X射线能谱（EDS）法快速无损检测卷烟纸中K和Na元素实际总含量的方法。利用EDS和传统的原子吸收光谱（AAS）法分别对卷烟纸表面K和Na元素含量（c）和实际总含量（C）进行了定量检测，探寻EDS法和AAS法定量检测结果间的关联。结果表明，这两种方法获得的数据之间具有如下关系：和，其相关系数R2分别为0.958和0.959。鉴于EDS具有快速、无损检测的优点，该方法通过快速的EDS表面分析可以实现对卷烟纸中K和Na元素总含量的检测，可有效提高测定卷烟纸中K和Na元素助剂添加量的实验效率。 |
| Abstract: |
| In this study, an energy dispersive spectrometer (EDS) method for rapid and non-destructive determination of K and Na elements in cigarette paper was reported. It was found that there was a linear relationship between the relative contents (c) of K and Na on the surface of cigarette paper measured by EDS and the actual contents (C) of K and Na in cigarette paper measured by conventional atomic absorption spectrometry (AAS), from which the following equations were established and, with the correlation coefficient of 0.958 and 0.959, respectively. Since the EDS method could conduct non-destructive testing on the solid sample without any pretreatment, it could be an efficient way for rapid determination of the contents of K and Na in cigarette paper. |
