石墨炉原子吸收光谱法直接测定血中铅OA北大核心CSTPCD
Direct Determination of Lead in Blood by Graphite Furnace Atomic Absorption Spectrometry
[目的]建立稀硝酸稀释血样,石墨炉原子吸收直接测定血铅的方法.[方法]采用1.0%硝酸10倍稀释血样,10 μL进样,标准加入法制备标准曲线,直接检测血铅.[结果]在实验条件下,血铅浓度在0.0-100.0μg/L之间存在线性关系(r=0.9992).铅标准溶液25.0、50.0、75.0μg/L几分别平行测定6次,其相对标准偏差为1.28%～2.74%.血样中加入铅标准溶液25.0、50.0、75.0μg/L几,测得血铅回收率为95.7%～10…查看全部>>
[ Objective ] To establish a direct blood lead determination methodology by graphite furnace atomic absorption spectrometry using nitric acid treated samples. [ Methods ] Blood samples were pre-treated by 0.1％ nitric acid and injected to a graphite furnace atomic absorption spectrometer. [ Results ] The linear range of proposed determination methodology was 0.0-100.0 μg/L (r= 0.999 2). The standard solutions containing lead at 25.0, 50.0 and 75.0 μg/L we…查看全部>>
