用火焰原子吸收光谱法测定酒精含量低的葡萄酒或啤酒等淡酒中的微量铅,文献已有报道。但这些文献多采用有机溶剂萃取法富集酒中微量铅,不适于酒精含量高的烈性酒小铅的測定。而有关后者的报道,则尚未见到。白酒系蒸餾酒,含铅量一般很低,通常近于ppb级。为使其浓度达到火焰原子吸收法的检测限,必须预先加以浓缩。同时,为保证测定的精密度和准确度,要求选定一组最佳的工作参数,以适应具体的仪器条件和工作条件。选择火焰原子吸收法的工作参数是一种多因素多水平试验。按照分析工作者的惯常 Flame atomic absorption spectrometry for the determination of trace amounts of lead in light alcohol, such as wine or beer, has been reported. However, these documents mostly use organic solvent extraction to enrich the trace lead in wine, which is not suitable for the determination of the small liquor with high alcohol content. However, the latter report has not been seen yet. Liquor distilled liquor, lead content is generally low, usually near ppb level. In order to reach the limit of detection by flame atomic absorption spectrometry, it must be concentrated in advance. At the same time, in order to ensure the accuracy and accuracy of the determination, it is required to select a set of the best working parameters to meet the specific instrument conditions and working conditions. The choice of flame atomic absorption method of working parameters is a multi-factor multi-level test. Follow the analyst’s habits
