Method 1631: Mercury in Water by Oxidation, Purge and Trap, and Cold Vapor AtomicFluorescence Spectrometry. Draft, January 1996

摘要

The method is for determination of total mercury (Hg) in filtered and unfilteredwater by oxidation, purge and trap, desorption, and cold-vapor atomic fluorescence detection. The method is designed for measurement of total Hg in the range of 0.2-100 ng/L and may be extended to higher levels by selection of a smaller sample size. The method includes suggestions for improvements in facilities and analytical techniques that should maximize the ability of the laboratory to make reliable trace metals determinations and minimize contamination.
