摘要:碳酸钙作为生产卷烟纸的填料,可以改善卷烟纸的透气度、调节卷烟纸燃烧速率,而钾、钠、镁的化合物作为卷烟纸的燃烧调节剂,直接参与燃烧,其含量会影响卷烟燃烧的烟气组分释放情况,进而影响卷烟的感官质量。因此,建立卷烟纸中Na+、K+、Mg2+、Ca2+含量的测定方法,对监控卷烟质量具有十分重要的意义。本研究利用离子色谱建立了同时测定卷烟纸中Na+、K+、Mg2+和Ca2+ 4种金属离子含量的方法。结果表明,卷烟纸中的4种金属离子含量在本方法下有很好的线性关系(R2>0.9995),检出限为0.01~0.03 mg/g,相对标准偏差小于5%,回收率在97.4%~106.2%。
Abstract:As a filler in the production of cigarette paper, calcium carbonate can improve the air permeability and adjust the burning rate of the cigarette paper, while the compounds of potassium, sodium and magnesium used as the combustion regulator in cigarette paper directly participate in the combustion, and the content of which will affect the release of smoke components from cigarette combustion, thereby affecting the sensory quality of cigarettes. Therefore, establishing a method for the determination of Na+, K+, Mg2+, and Ca2+ content in cigarette paper is of great significance for monitoring the quality of cigarettes. In this study, a method for simultaneously determining the contents of Na+, K+, Mg2+, and Ca2+ in cigarette paper was established by using ion chromatography. The results showed that a good linear relationship among the four metal ions was found with R2>0.9995,the detection limit 0.01~0.03 mg/g,the relative standard deviations <5%,and the recoveries of the ions 97.4%~106.2%.
