Scope

This Standard specifies the atomic fluorescence spectrometry for the determination of
mercury, arsenic, selenium, bismuth, and antimony in water.
This Standard applies to the determination of soluble [Translator: dissolved-state] and
total quantity of mercury, arsenic, selenium, bismuth, and antimony in surface water,
groundwater, sewage, and industrial waste water.
According to the method of this Standard, the detection limit of mercury is 0.04μg/L,
the determination lower limit of mercury is 0.16μg/L; the detection limit of arsenic is
0.3μg/L, the determination lower limit of arsenic is 1.2μg/L; the detection limit of
selenium is 0.4μg/L, the determination lower limit of selenium is 1.6μg/L; the detection
limit of bismuth and antimony is 0.2μg/L, the determination lower limit of bismuth is
0.8μg/L.
