试样经微波消解后,采用ICP-AES测定铜镏中多种常微量元素含量。实验结果表明,测定相对标准偏差均小于4.0%。回收率在96.5%—107.0%之间,方法简便,快速.可靠。
Samples after microwave digestion, the determination of trace elements by ICP-AES. The experimental results show that the relative standard deviations are less than 4.0%. The recovery rate of 96.5% -107.0%, the method is simple, fast and reliable.
