Sažetak
U radu je predložena metoda za određivanje salicilne kiseline (SA) u vinu koja se zasniva na reakciji izmene liganada. Reakcija je praćena spektrofotometrijski, merenjem brzine obrazovanja kompleksa između mangana i salicilne kiseline u baznoj sredini na 370 nm. Korišćenjem metode početnih brzina kostruisana je kalibraciona prava, koja je linearna u opsegu koncentracija 0,69-4,14 μg mL-1. Optimizovanjem uslova metode, dobijene su vrednosti za granicu detekcije ( 10S0 kriterijum) i granicu određivanja ( 3,3S0 kriterijum) od 0,11 μg mL-1 i 0,33 μg mL-1, respektivno. Razvijena metoda je primenjena za određivanje salicilne kiseline u uzorcima vina. Dobijeni rezultati su poređeni sa rezultatima dobijenim HPLC hromatografijom, pri čemu je pokazano da postoji dobro slaganje između dva niza rezultata.
