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

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.
