标准摘要
[中文适用范围]: 该方法的原理是用酸消化过滤器上收集的颗粒材料,溶解存在的任何铅并通过原子吸收光谱法(AAS)分析样品溶液。 该方法适用于含有颗粒铅含量的环境空气样品,如果使用火焰原子吸收光谱法,过滤器上收集到的沉积颗粒铅量大于1镕。 石墨炉原子吸收光谱法的最终测定允许测量小于1镕的数量,但仅在检测限经过实验验证后才适用。 [外文原描述]: The principle of the method specified is based on digesting with acid the particulate material collected on a filter, solubilizing any lead present und analysing the sample solution by atomic absorption spectrometry (AAS). The method is applicable to ambient air samples with particulate lead contents, such that the amount of deposited particulate lead collected on the filter is greater than 1 µg if flame AAS is used. Final determination by graphite furnace AAS allows measurement of quantities of less than 1 µg, but is only applicable after experimental validation of detection limits.
