摘 要: 利用电感耦合等离子体原子发射光谱法测定了矿泉水及饮用水中的铝、铬、锰、汞、镉、铅、镁等7种元素的含量。结果表明:标准曲线的线性关系良好,检出限为0.000 9-0.075 9μg/mL,精密度为0.53-2.42,加标回收率在101.2%-106.5%之间。 Seven trace elements of Al、 Cr、 Mn、 Hg、 Cd、 Pb and Mg in mineral water were determined directly by Inductively coupled plasma atomic emission spectrometry(ICP-AES).The results showed that there was a good linearity of standard lines,the limit of examined elements was 0.000 9-0.075 9 μg / mL,the precision between 0.53- 2.42 and the recovery between 101.2%-106.5%.
