Abstract

A method is suggested for the determination of submicrogram Cd in quantities by isotope dilution, using substoichiometric extraction into dithizone in chloroform. The applicability of the method was tested in biological samples. Extraction was carried out from a sodium acetate buffer betweenpH 9.7 and 12.0. With amounts of 0.2 μg of Cd, the S.E. was not greater than 0.01 μg. This method is suitable for large scale analysis of trace amounts of Cd in biological materials.
