摘　　要：本文对经压力消解器密闭消化后的小鼠脑及血样品,采用电热原子吸收光谱法(ETAAS),进行了铝含量的测定,以标准曲线法定量,其线性范围为0——200ppb。方法精密度c=4.9％,准确度是通过测定GBW09101人发标准物质来验证的。检出限为4.7ng^(Al)/ml。The amounts of aluminium in mice' s brains and blood, digested in a pressed digester, have been detected by Electric Thermic Atomic Absorption Spectrometry(ETAAS). The linear range of the standard curve used in the analysis was 0 -200 ppb. The precision of the method is 4. 9% and detection limit 4. 7 ng Al/ml which has been tested with standard substance of GBW09101 human hair.
