Fundamental studies of photometric determination of tellurium were made by precipitating the tellurium with sodium diethyldithiocarbamate and extracting it with organic solvent, using mainly Pulfrich's photometer. It was found that the best extracting solvents were benzen and chloroform, and the range of suitable concentration of acid for complete extraction was from pH 3.32 to 5N of sulfuric acid. In the case of application of this method, the separation of microamount of tellurium in iron and steel was made by reducing its acidified solution with stannous chloride for deposition of metallic tellurium. Various suitable conditions were investigated for proposal of the analytical procedure of tellurium in iron and steel. The time required for this method was about 2 hours.
