• A method of selective separation and determination of iodine on a semimicro scale in organic compounds containing chlorine or bromine has been established. The decomposition of the sample was effected by the use of sodium peroxide and a microbomb. Some improvements were made in the mixing of the sample and the sodium peroxide. The product of decomposition was dissolved in water, the hydrogen peroxide was driven off by gentle boiling with platium foil, and the solid impurities were filtered off. The pH of the filtrate was then adjusted to below 1 with conc HCl. PdCl<SUB>2</SUB> and hydrazine were added, and the precipitate of PdI<SUB>2</SUB> was let stand for 1 day, then filtered, washed, and dried. The errors were less than 0.3 %.
