Abstract: A method of releasing Co from vitamin B12 by 1 hr. ozonization was described. Co is detd. by isotopic diln. analysis or by complexometric radiometric titrn. From the amt. of Co detd., the amt. of vitamin B12 is calcd. With this method, the metal contamination occurring with the application of 5N HCl for releasing Co is eliminated. App. for the ozonization and kinetics of the decompn. of vitamin B12 are described.
