A new method for the determination of urinary lead by means of the emission spectroscopy is described. The sample is concentrated by lyophilization and the homogeneous dust obtained is analysed using the "double arc" method. The matrix effects and the source unstability are compensated by the use of the internal standard. The influence of the volatilization of the elements of the analytical pairs are studied and the pair thallium-lead is selected. The method is reproducible and the detection limit is 5 microgram/l of urinary lead.
本文描述了一种通过发射光谱法测定尿铅的新方法。样品通过冻干浓缩，所得均匀粉尘用“双电弧”法进行分析。使用内标补偿基体效应和光源不稳定性。研究了分析对中元素挥发的影响，选择了铊-铅对。该方法具有可重复性，尿铅的检测限为5微克/升。
