ANALYSIS OF ORGANOMERCURY WITHIN BIOLOGICAL SAMPLES BY GOLD AMALGAMATION-ATOMIC ABSORPTION SPECTROSCOPY

摘要

PURPOSE: A quantitation method of organomercury in a biological sample is provided to remove spectral interference factors due to a medium, and to draw reliable result. CONSTITUTION: A quantitation method of organomercury in a biological sample comprises: a step of adding hydrochloric acid to the biological sample and preparing digestive fluid; a step of adding an organic solvent to the digestive fluid and extracting an organic layer; a step of adding a solution of a thiol compound to the extracted organic layer, and extracting a thiol compound layer; a step of performing thermal decomposition of an analyte contained in the thiol compound layer, and contacting a gold collector with vapor generated by thermal decomposition; and a step of heating the gold collector.
