| 摘 要： | 烟叶中的镁元素用乙酸萃取、原子吸收光谱法测定,并与行业标准方法YC/T 175-2003进行比较,结果发现乙酸萃取-原子吸收法与行业标准法测定的数据吻合.同时对国家烟草标准物GBW08514、GBW08515及茶叶标准物GBW08513进行测定,证明其测定数据与标准值相符.此方法把烟草中的镁、水溶性糖、烟碱及氯离子的处理方法有机地结合在一起,使烟草中镁的检测变得简单、快速;且方法污染小、操作简便,适合大批量烟草样品中镁的快速检测.

| Abstract: | Mg element in tobacco was extracted by acetic acid and determined by AAS. The results are identical with those obtained by the method of tobacco standard YC/T 175-2003. For standard samples GBW 08514,GBW 08515 of tobacco and GBW08513 of tea determinations, the results are in accordance with the standard values. The processing of this method can be combined with water soluble sugar,nicotine and chloride,making the determination of magnesium in tobacco simple, brief, fast and safe. This method is suitable for the determination of Magnesium in large quantities of samples. |
