Notes: A flameless atomic absorption method for the determination of small amounts of mercury in solutions is described. The mercury is amalgamated quantitatively on a copper wire and subsequently vaporized in an absorption cell which is placed in the light path of a commercial atomic absorption instrument. The mercury vapor can be quantitatively determined by its absorption of the 253.7 nm mercury line. The method has a detection limit of 0.2 ng and is therefore about 10000 times more sensitive than atomic absorption analysis using flame atomization.
