本文报道了用自装无焰原子吸收测汞仪与铜丝电解汞齐化富集相结合,对某些天然水(海水、地下水、井水、池水等)中痕量汞进行无焰原子吸收测定。测定灵敏度为0.05微克/升/1％;检出限量为0.08ppb;测定范围为0.08—1.5ppb;测定水样体积为25毫升。
In this paper, a flame atomic absorption spectrophotometry (HFA) with self-contained flameless atomic absorption mercury detector and amalgamation of copper wire are reported. Flameless atomic absorption of trace mercury in some natural water (seawater, groundwater, well water, Determination. The assay sensitivity was 0.05 μg / L / 1%; the detection limit was 0.08 ppb; the measurement range was 0.08-1.5 ppb; and the water sample volume was determined as 25 mL.
