A method is described to determine mercury in water and urine that employs a carbon-furnace atomizer atomic absorption technique. Findings show that a matrix of 5% nitric acid (HNO/sub 3/) and 0.1% potassium dichromate (K/sub 2/Cr/sub 2/O/sub 7/) stabilize the mercury, allowing a pyrolyzation temperature of up to 300/sup 0/C. In this procedure the mercury is atomized before most of the matrix, thereby minimizing potential interferences. The applicability of this method for the determination of organic mercurials is investigated.
