Spectrophotometric Determination of Titanium as a Mixed Thiocyanate-1-phenyl-2-methyl-3-hydroxy-4-pyridone Complex

The extn. of titanium(IV) thiocyanate complex by 1-phenyl-2-methyl-3-hydroxy-4-pyridone(HX) dissolved in chloroform has been investigated from hydrochloric and sulphuric acid solns. The extd. complex has the ratio Ti : SCN : HX 1 : 2 : 2. Chloroform solns. follow Beer-s law and are stable for at least 24 h. A sensitive and reproducible spectrophotometric detn. of titanium is possible. The molar absorptivity of the method is 26500 l mol(-1) cm(-1) at 365 nm. Few metals interfere, and their sepn. is discussed.
