The determination of silver in animal tissues by a wet-oxidation process followed by atomic-absorption spectrophotometry

Abstract

Silver in animal tissues can be determined at fairly low levels by conventional atomic-absorption spectrophotometry, following wet oxidation. The wet-oxidation stage is difficult when large samples are to be analysed and the final solution must be adjusted in order to minimise losses of silver by adsorption or precipitation. The method has been applied to samples of urine, faeces, individual organs, skin and whole-animal homogenates.
