Using of a Hitachi EPB-U type spectrophotometer, critical studies have been made of the ferric, titanium and thiocyanate systems in aquous solution. From the determined several spectral transmission curves, of which those shown are representative, the following conclusions are obtained. (1) Various formulas have been assigned to the colored complex present in aqueous solutions of thiocyanate systems. Our experiment also indicates the behaviour of color compounds are very complex. But obeys Beer's low in a certain region. (2) Relating to the use of thiocyanate method for the determination of iron in titanium, interference by the complex of titanium and thiocyanate a certain spectral band region in 0.7-1.0NH₂SO₄ acid solution is negligible.
So that, the thiocyanate method can be use as control methods in commercial operation using a certain spectral band region.
