摘要
本文采用微波消解和 ICP- AES法 ,同时测定花岗石样品中的铅、镉、铬、砷 4种有害元素。检出限分别为 0 .0 0 0 8、0 .0 0 0 7、0 .0 0 18、0 .0 0 12 μg·m L-1,回收率为 93.4 %— 10 2 .5 % ,RSD为 1.3%— 3.6 %。该法准确、快速、简便 。
The paper develops a new method of microwave digestion\|ICP\|AES for simultaneous determin ation Pb,Cd,Cr and As.Under the optimum condition,the detection limits of Pb,Cd,Cr and As are 0.0008,0.0007,0.0018 and 0.0012μg·mL -1 ,respectively.The recoveries of the method are in the range of 93.4%_102.5%,RSD is in the range of 1.3%_3.6%.This method is accurate,rapid and convenient with satisfactory results.
