A method for the determination of cadmium in bone by the flameless atomic absorption spectraphotometry was studied. Because calcium and phosphorus in the bone digested solution interfered with the determination of cadmium, removal of these elements from the bone digested solution was examined. Calcium and phosphorus were removed from the bone digested solution, former as calcium sulfate with sulfuric acid and the latter as ammonium molybdophosphate with ammonium molybdate. Thereafter, cadmium was extracted with the system of diethyldithiocarbamate-methylisobutyl ketone extraction and the organic layer was applied to the flameless atomic absorption spectrophotometry. The recovery by this procedure was 70-80%, and 10 to 100 ng of cadmimm per g of bone was able to be determined.
