Oxygen determination in thallium and thallium compounds was investigated by a modification of the Schutze-Unterzaucher method. When oxygen in thallium compounds was determined by the conventional method for organic compounds, the oxygen content in almost all samples was 1-5% less than the calculated value. A silica tube that was used for heat decomposition was subjected to erosion by thallium (I) oxide produced by the pyrolysis of thallium compounds and cracks were caused. In order to prevent this, the inside wall of the silica tube was coated with carbon which had been produced by the pyrolysis of naphthalene. Carbon powder was also added into the sample boat to reduce thallium oxides formed by the decomposition of thallium compounds. All of the oxygen in thallium and thallium compounds was determined according to the proposed method, and quite favorable results could be obtained. About 40 min was required for one determination.
