“…Separations of radioiodine that have been made specifically from milk include ion exchange on synthetic resins (3,5,6,9,11), solvent extraction (2, 12), and electrodialysis (10). Inorganic iodide separations that have been applied to both biological and nonbiological samples include ion exchange on synthetic resins; coprecipitation with, or ion exchange on, silver chloride; isotopic exchange on silver iodide; and solvent extraction.…”

b Iodine-131, as iodide ion, is separated from other milk constituents by ion exchange on a silver chloride column. After elution as iodic acid from the column by acidified chlorine water, the eluate can b e directly analyzed by gamma counting. The time required to analyze a 1-liter sample by this method is approximately 30 minutes (exclusive of counting time). If beta counting or increased sensitivity is required, the iodine is subjected to two oxidation-reduction solvent-extraction cycles and finally precipitated as silver iodide prior to counting. Chemical and radiochemical yields for both added and metabolized iodide are identical, and are 90 to 95% for homogenized milk and 85 to 95% for raw milk.Total time for the complete procedure (exclusive of counting time) is approximately 2 hours for a single sample. Less than 2 picocuries of total iodine-131 can b e detected in 1 liter of milk, using the complete procedure. The application of the procedure to other materials is discussed.O D I N E -~~~ is an important radio-
