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. Elohopea. Määrittäminen me-ren antimissa "Flow injection" -kylmähöyryatomiabsorptioteknii-kalla (FI-CVAAS) mikroaalto-digestion jälkeen.(NMKL 170, 2002))
