微波消解原子荧光光度法测定水产品中的铅

Determination of lead in aquatic products by atomic fluorescence spectrometry

采用微波消解技术处理样品，用原子荧光光谱法测定水产品中痕量铅，讨论并确定了最佳测定条件。结果表明，铅测定的线性范围为0～100．00μg／L，相对标准偏差1．12％，回收率为87．47％～109．60％，本方法简便、快速，可用于水产品中铅的测定。

The microwave assisted sample digestion was applied to the AFS determination of lead in aquatic products. The linear range for detection of lead was 0 - 100 μg/L, the recovery rate was 87.47% - 109.60% and the RSD was 1.12% .This method is accurate, low toxic, convenient and suitable for measurement of lead in acidic solution.
