超声提取-连续流动法快速测定卷烟纸中钾、钠和钙的含量

摘要

In order to monitor cigarette paper quality, the contents of potassium (K), sodium (Na) and calcium [Ca) in cigarette paper were rapidly determined by ultrasonic extraction-continuous flow method. The recoveries of K, Na and Ca were 99.2%, 98.6% and 101%, with the relative standard deviations (RSD) of 2.32%, 2.09% and 3.06%, respectively. This method is simple, fast and accurate, and competent for determining potassium, sodium and calcium in cigarette paper.%为了控制卷烟纸的质量,需要快速分析卷烟纸中钾(K)、钠(Na)和钙(Ca)含量,采用超声提取-连续流动法快速测定卷烟纸中K,Na和Ca含量,方法的回收率分别为99.2％,98.6％和101％,相对标准偏差( RSD)分别为2.32％,2.09％和3.06％.方法具有操作简单、准确、快速等优点,适合于卷烟纸中K,Na和Ca的含量分析.
