超声提取-电感耦合等离子体质谱法快速测定卷烟纸中钾、钠、钙、镁的含量

Rapid Determination of Potassium, Sodium, Calcium, and Magnesium in Cigarette Paper with Ultrasonic Extraction-Inductively Coupled Plasma Mass Spectroscopy Method

摘要: 采用超声提取-电感耦合等离子体质谱法能快速测定卷烟纸中钾（K）、钠（Na）、钙（Ca）、镁（Mg）含量，控制卷烟纸的质量稳定性。检出限分别为2.46、0.44、8.84、0.28 µg/L；回收率90.3%~109.0%；相对标准偏差（RSD）<5%。此方法具有操作简单、准确、快速等优点，适合于卷烟纸中K、Na、Ca、Mg含量的分析。

Abstract: In order to monitor cigarette paper quality, the contents of potassium (K), sodium (Na), calcium (Ca) and magnesium (Mg) in cigarette paper were rapidly detected by ultrasonic extraction-inductively coupled plasma mass spectroscopy method. The LODs of K, Na, Ca and Mg were 2.46, 0.44, 8.84 and 0.28 µg/L, respectively. The recoveries were in range of 90.3%-109.0%, with RSD less than 5%. This method is simple, fast and accurate, and suitable for detecting K, Na, Ca and Mg in cigarette paper.
