When titanium was reduced directly by liquid zinc amalgam and titrated with standard ferric solution immediately after the dissolution of steel sample, the presence of 0.15 per cent of arsenic caused about 0.03 per cent high result for titanium. So the removal of arsenic as arsenic tribromide with bromine in hydrochloric acid solution was recommended. In the gravimetric or volumetric determination after the separation of titanium with sodium thiosulfate or ammonium phosphate, there was no interference by arsenic. For the determination of molybdenum in the volumetric method, it was necessary to remove arsenic as tribromide. In the gravimetric method with α-benzoin oxime, however, arsenic had no influence.
