摘要
研究了微波制样,用ICP—AES法(电感耦合等离子体发射光谱法)同时测定珍珠白样品中Mg、Al、Pe、Pb、Cr、Ni、Mn、As8种微量元素的新方法。方法的检出限为0.002～0.036μg/mL,回收率为92.8％～107.6％,RSD小于3.19％。该法准确、快速、简便,应用于花岗石的测定,结果满意。
The essay develops a new method of microwave degestion with a sample of ICP - AES simultanuously determining eight trace elements such as Mg, Al, Fe, Pb, Cr, Ni, Mn and As. The detection limits of the method is 0.002-0.036 μg/mL. The recycling rate ranks from 92.8% to 107.6% . RSD is less than 3.19% . This method is accurate, quick-acquired and convenient. It is used in the determination of granite with the result being satisfactory.
