A rapid polarographic method for the determination of titanium, in the range of 0.1 to 5% in tantalum and niobium concentrates ard ores is described. The supporting electrolyte is 5.4M sulfuric acid and O.2M potassium pyrosulfate. No chemical separation is necessary. Tantalum, niobium, iron, tin, manganese, and tungsten do not interfere. Molybdenum gives a reduction wave in the same region as titanium and will interfere if present in appreciable amounts. Vanadium in appreciable amounts shows no evidence of a wave but does enhance the titanium diffusion current. However, these two elements are not normal constituents of tantalum and niobium concentrates and ores. (auth)
