An indirect method has been developed for Ti(IV) determination at trace levels, by means of the formation of 11‐molybdotitanophosphoric acid, its isolation with an organic solvent, stripping with alkali, and measurement of the Mo(VI) by its catalytic effect on the polarographic reduction of hydrogen peroxide. A detection limit of 4.09 μg/liter can be achieved. The procedure has been applied successfully to a certified steel sample.
