Determination of trace amounts of mercury in sea water by graphite furnace atomic-absorption spectrophotometry

M. Filippelli  

Abstract

A procedure for the determination of mercury(II) in inorganic and organomercury salts in sea water by carbon furnace atomic-absorption spectrophotometry at the nanogram level is described. Mercury(II) was concentrated using the ammonium tetramethylenedithiocarbamate (ammonium pyrrolidinedithiocarbamate, APDC)-chloroform system, and the chloroform extract was introduced into the graphite tube. A linear calibration graph was obtained for 5–1 500 ng of mercury in 2.5 ml of chloroform extract. Because of the high stability of the Hg(II)-APDC complexes, it is possible to evaporate the extract in order to obtain a crystalline powder to be dissolved with a few microlitres of chloroform. In this way Hg(II) can be detected at the sub-nanogram level.
