Abstract:
Micro-analytical methods for the determination of iodine in biological substances are discussed and the efficiency of the nickel dish method compared with that of the dry oxidation in a closed system. It is shown that under the conditions specified the error in duplicate analyses does not exceed 20 per cent., while over 80 per cent. of the total iodine present, i.e. iodine in the original material plus the amount added, can be recovered.
