摘要
建立了一种应用原子荧光光谱法同时测定饮用水中铅和总砷含量的方法.结果表明,通过优化得到检测条件为铁氰化钾浓度 1.00%,硼氢化钾浓度 1.50%,硫脲浓度 1.00%.铅和砷在 0～10 μg·L-1 时,线性关系良好,方法检出限分别为 0.10 μg·L-1 和0.15 μg·L-1,加标回收率为98.4%～103.3%.该方法节省了成本,提升了饮用水中铅和总砷的检测效率,适合在基层实验室中推广应用.
Abstract
In this study,a method for simultaneous determination of lead and total arsenic in drinking water by using atomic fluorescence spectroscopy was established.The results showed that the optimal conditions were obtained with a K3[Fe(CN)6]concentration of 1.00%,a KBH4 concentration of 1.50%and a thiourea concentration of 1.00%.The linear range was good at 0～10 μg·L-1 for both lead and arsenic,and the detection limits were 0.10 μg·L-1 and 0.15 μg·L-1,respectively.The recovery values were 98.4%～103.3%.The proposed method saves cost,improves the detection efficiency,and is suitable for popularization and application.
