Method 7471B

Mercury (Hg)


This method is a cold-vapor atomic absorption procedure for measuring the Mercury in soils, sediments, bottom deposits, and sludge-type materials.

This method uses cold-vapor atomic absorption and is based on the absorption of radiation at the 253.7-nm wavelength by mercury vapor. The mercury is reduced to the elemental state and aerated from solution in a closed system. The mercury vapor passes through a cell positioned in the light path of an atomic absorption spectrophotometer. Absorbance (peak height) is measured as a function of mercury concentration.
