摘要
目的：探索并建立快速测定头发中铁锰铜锌含量的方法。方法：微波消解头发样品,用ACP-AES法测定头发中微量元素铁锰铜锌。结果：标准曲线在0.1~1.0×10-6范围内线性良好,相关系数均为0.999以上,测定方法检出限不大于4.5μg/L,测定值均在标准物质标准不确定范围内,相对标准偏差均小于6%。结论：方法适于头发中多种微量元素的测定。
Objective：To deveplp amethod for rapid detection of multiple microelements in Hair samples. Methods：Microwave heating of hair sample digestion,iron,manganese,copper,zinc were determined by inductively coupled plasma atom emission spectrum. Results：The standard curve is linear in the rang of 0.1 - 1.0 × 10^-6, correlation coefficientr is more than 0. 999. The results were all within uncertainty of the certified value of national reference materials. The relative standard deviations were all less than 6 %. Conclusion ： The method is rapid, simple and have satisfied accuracy and precision and it is suitable for determining iron, manganese, copper and zinc.
