1 Application scope This standard specifies atomic fluorescence spectrometry for determining mercury, arsenic, selenium, bismuth and antimony in water. It is applicable to the determination of total quantity of soluble mercury, arsenic, selenium, bismuth and antimony in surface water, groundwater, domestic sewage and industrial wastewater. For mercury, the detection limit by the method in this standard is 0.04μg/L, and the lower limit of determination is 0.16μg/L; for arsenic: 0.3μg/L and 1.2μg/L; for selenium: 0.4μg/L and 1.6μg/L; for bismuth and antimony, 0.2μg/L and 0.8μg/L. 2 Normative references The following documents or provisions therein are quoted in this standard.
