Mercury. Determination in Seafood by Flow Injection Cold Vapour Atomic Absorption Spectrometry (FI-CVAAS) after Microwave Digestion. (NMKL 170, 2002)
The method is applicable for the quantitative determination of mercury in fish and various types of seafood products. The method has been tested on
concentrations higher than 0.04 mg/kg dry products.
Concentrated nitric acid and hydrogen peroxide
(30%) are added to test samples, which are then
digested in a microwave oven. The concentration of
mercury is determined by FI-CVAAS after divalent
mercury is reduced to elemental mercury with
sodium boron hydride.
