EPA 7473

Mercury in Solids and Solutions by Thermal Decomposition, Amalgamation, and Atomic Absorption Spectrophotometry

Applicability: EPA Method 7473 is applicable for determining total mercury in various sample types, including solids, aqueous solutions, and digested solutions, both in laboratory and field settings. It’s particularly useful for samples like soils, sediments, bottom deposits, sludge, aqueous wastes, and groundwater.

Purpose: EPA Method 7473 is used to determine the total mercury content in both solid and liquid samples.
