摘要
采用直接固体进样-石墨炉原子吸收光谱法测定茶叶中铅含量,无需繁琐的样品消解过程,称样量小,方法简便,准确度较高,可实现铅的快速分析。本方法中铅的检出限为0.021ng,相对标准偏差为7.72%。
The content of Pb in tea was determined by direct solid sampling CFAAS without complex digestion .Themethod of rapid analysis for lead easy in operation and higher accurate in outcome with lrttle quantity .The detection limit of the method for lead was 0.021ng,whit precision of 7.72%RSD
