We describe procedures for direct determination of lead and cadmium in blood and urine by flameless atomic absorption spectrophotometry. Before analysis, the samples are pre-ashed in microboats in an ordinary laboratory oven. In this way, many samples can be prepared and pre-ashed simultaneously. We find the procedures presented in this work to be rapid, accurate, and precise.
我们描述了通过无火焰原子吸收分光光度法直接测定血液和尿液中铅和镉的方法。分析前，将样品在普通实验室烘箱中的微型舟皿中进行预灰化。通过这种方式，可以同时制备和预灰化许多样品。我们发现本文介绍的方法快速、准确且精密。
