摘要
拟定了用HNO3-H2 O2 消化样品 ,以钯盐作基体改进剂 ,用石墨炉原子吸收测定饮用水中Pb和Cr的分析方法。Pb ,Cr的检出限分别为 0 0 0 8,0 0 3μg/L ,对含 1 0 μg/L的Pb ,2 0 μg/L的Cr的合成水样的相对标准偏差分别为 1 9%与1 6%。
A method for the determination of lead and chromium in drink water by graphite furnace atomic absorption spectrometry has been presented. The samples were digested by the mixture of HNO 3 and H 2O 2 and palladic salt was used as a matrix improver The detection limits for lead and chromium were 0 008 and 0 03μg/L,respectively The relative standard deviations were 1 9% and 1 6%,respectively
