Sažetak

A polarographic method for direct determination of cadmium in urine and blood is described. In urine cadmium is quantitatively precipitated by calcium chloride in a weakly acid medium. The precipitate is separated by the procedure of centrifugation. The content of organic matter in the precipitate is mineralized by perchloric acid. A blood sample is partly mineralized by nitric acid iron is transformed into chloride and extracted by means of ethyl ether together with the fat matter. Complete mineralization can be done with sulphuric and perchloric acid. The mineralized residue is dissolved in 1 M NaCl and cadmium is determined by polarography.
