Abstract

Kromatografija je jedna od najvažnijih metoda u analitičkoj kemiji budući da ima veliku moć separacije, čak i kada se radi o kompleksnim uzorcima, te istovremeno omogućuje odjeljivanje, identifikaciju i kvantitativno određivanje sastojaka u uzorcima. Ukoliko se u uzorku nalaze ionske čestice i/ili polarne molekule, koristi se ionska kromatografija (eng. ion chromatography, IC) u kojoj se odjeljivanje uglavnom temelji na razlici u afinitetu sastojaka uzorka prema ionskoj izmjeni na nepokretnoj fazi. Poput mnogih drugih modernih kromatografskih tehnika, ionska kromatografija može se koristiti za analizu tvari u poprilično različitim matricama, no najzastupljenije su ipak vodene otopine. Tako je i tema ovog diplomskog rada upravo analiza nekolicine anorganskih aniona u realnim uzorcima voda, bilo da se radi o prirodnim vodama ili komercijalnim vodama dostupnim u prodaji. Samoj analizi prethodio je razvoj metode s detaljno provedenom validacijom.

Abstract (english)

Chromatography is one of the most important methods in analytical chemistry due to its great separation power even in cases when complex samples are to be analyzed. At the same time it enables simultaneous separation, identification and quantitative determination of components in samples. Ion chromatography is used in cases when sample includes ion particles and/or polar molecules. In ion chromatography separation mainly occurs as a consequence of different affinities of components to exchange with the ions from stationary phase. Ion chromatography can be applied for analysis of different matrices, jet water samples are the most common ones. The analysis of natural water samples and samples of commercial waters are topic of this work also. During the experimental, ion chromatographic method was developed and an extensive validation performed.
