Sažetak

Predložena je nova, brza i precizana spektrofotometrijska metoda (koja ne zahteva ekstrakciju), zasnovana na primeni N'-(2-hidroksibenziliden)-3-oksobutanhidrazida (HBOBH) kao reagesa, za određivanje mikrokoličina titana(IV). Pod unapred određenim optimalnim uslovima, pokazano je da u opsegu od 1,757 do 17,57 μg mL-1 absorbanca linearno raste sa porastom koncentracije titana(IV). Utvrđeni su i parametri metode kao što su molarna apsorptivnost, Sendel-ova osetljivost, stehiometrija kompleksa, granica detekcije i granica kvantifikacije. Reproduktivnost metode je bila odlična, a 'recovery' se kretao u opsegu od 102 do 104%. Predložena metoda je primenljiva za određivanje titana(IV) u sintetičkim smešama i legurama.
