摘要
用 ICP- AES法测定硫酸铜中的铅、镉、铝等 12种微量元素 ,钇作内标校正大量铜基体的干扰。加标回收率 93.5 %— 10 5 % ;相对标准偏差 0 .4 1%— 3.6 1%。方法简便、快速、准确 。
A method of the determination of 12 microelements in copper sulfate by ICP-AES was established.The interference effect of matrix was effectively corrected by Y as the internal standard.The recovery rates are in the rang of 93.5%-105% with RSD of 0.41%-3.61%.The method is accurate,rapid and simple,and the detection limit meets the need of daily analysis.
