Some improvement was attempted in the Schütze method for determination of oxygen in organic compounds by oxidizing carbon monoxide with iodine pentoxide and measuring the weight of carbon dioxide thereby formed. A new type of filling tube, which can be heated from inside, was used for the oxidation, and a method of preparing iodine pentoxide to be placed in the lower layer of the tube and silver granules to be filled in the upper layer was examined. Conditions for determination was examined for burning the sample by heating the oxidation tube to 150° from inside, and the life of silver granules was also examined. The advantage or disadvantage of this method was compared with the generally practiced iodometry and heated silver method.
