The principle of the method specified is dissolving a test portion in hydrochloric and nitric acids, removing hydrochloric acid and nitric acid by evaporation to fumes in the presence of sulfuric acid, forming the titanium diantipyrylmethane complex, measuring the absorbance of the test solution at a wavelength of 390 nm. The method may be used to determine titanium contents in the range of 0,3 % (m/m) to 5,0 % (m/m). Evidence exists that extension of this method is possible for titanium contents down to 0,05 % (m/m); modifications allow to determine titanium in alloys containing tungsten and/or tantalum.
