Determination of Bismuth and Tellurium in Tissues by Atomic Absorption Spectrophotometry

Abstract

Abstract An atomic absorption method for the determination of bismuth and tellurium in animal tissue is described. Samples were wet-ashed with nitric acid. A hydrochloric acid solution, containing 4 mg of tissue ash per milliliter of solution, is used for the determination of bismuth and tellurium. No chemical separations are used. Effects of total salt concentration on the determination, recovery data from spiked samples, and precision of the method are discussed. Concentrations as low as 1.5 μg of bismuth and 2.0 μg of tellurium can be determined in 1 gm of animal tissue.
