Sažetak
Titanium(IV) in sulphuric, perchloric and hydrochloric acid media reacts with 3-hydroxy-2-methyl-1-(4-tolyl)-4-pyridone (HY) to give a complex which is extractable into chloroform. The composition of the extractable complex depends on the acidity of te aqueous phase and on which mineral acid is used. The mixed titanium-perchlorate-HY complex which is formed in the presence of excess of perchlorate is the most suitable for the spectrophotometric determination of titanium. The molar absorptivity of the complex is 1.6 x 10(4) l mol(-1) cm(-1) at 355 nm. The optimum titanium concentration range is 0.5-6 micro g/ml. The method has been successfully applied to the determination of titanium in samples of bauxite and alumina refractory.
