The authors experimentally study the separate stages of the determination of iodine in thyroidin by the combustion method in a flask with oxygen. The monotypic, conventional procedures and the procedure of Kolii and Pakhomov were studied. With addition of potassium iodide, a sixfold amount (compared with the initial) of iodine is liberated. Further, the liberated iodine is titrated by sodium thiosulfate. The authors find the degree of influence of a high nitrogen content on the determination of iodine in organic compounds. The procedure developed for the quantitative determination of the iodine in thyroidin by the combustion method is simple, fairly rapid, and can be used for the reliable control of the quality of thyroidin preparations and its starting raw material.
