The authors analyze biological materials containing less than 2.10/sup -6/ g/g of iodine, using radiochemical separation, which enabled its determination down to 10/sup -9/. The method involved mineralizing samples by fusion with NaOH, carrying out a redox cycle with NaNO/sub 2/ and Na/sub 2/SO/sub 3/, extraction of elemental iodine with carbon tetrachloride, and precipitating the I as AgI. Methods have also been developed for the determination of both total and progeinbound iodine in urine.
