摘要
目的：建立新的试样处理方法测定白酒中的铅。方法：石墨炉原子吸收光谱法测定。结果：简化前处理方法,标准曲线相关系数为0.9992,相对标准偏差0.96%,平均回收率为94.4%-106%。结论：该法准确度、精密度良好、灵敏度高,是简便、快速、实用的测定白酒中铅的方法。
Objective：To develop a new method to detect white liquor the lead.Methods：Graphite oven atom Absorption spectrographic methods was used for determination.Results：The correlation coefficient was 0.9992,RSD was 0.96%,Average returns-ratio was 94.4%-106%.Conclusion：This method is accurate,sensitive and simple.
