Sažetak

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 26 500 1 mo1-1 cm-1 at 365 nm.
Few metals interfere, and their sepn. is discussed.
