Abstract

Ionska kromatografija najčešće je primjenjivana za praćenje kvalitete vode (prisutnost različitih iona u vodi) te općenito za monitoring okoliša (praćenje onečišćivala), upravo zahvaljujući njenoj visokoj osjetljivosti, preciznosti i mogućnosti istovremene analize više iona. Cilj ovog diplomskog rada bio je provesti validaciju metode ionske kromatografije za određivanje aniona (bromida, fluorida, fosfata, klorida, nitrata, nitrita i sulfata) i kationa (amonija, kalcija, kalija, magnezija, natrija i litija) u pripremljenim otopinama poznatih koncentracija. Određeni su parametri validacije: linearnost, preciznost, istinitost (točnost), granica detekcije i kvantifikacije.

Abstract (english)

Ion chromatography is most often used to monitor water quality (presence of different ions in water) and for environmental monitoring in general (monitoring of pollutants), thanks to its high sensitivity, precision and the possibility of simultaneous analysis of several ions. The aim of this thesis was to validate the method for determining anions (bromide, fluoride, phosphate, chloride, nitrate, nitrite, and sulfate) and cations (ammonium, calcium, potassium, magnesium, sodium, and lithium) in prepared solutions with individually known concentrations using the ion chromatography method. Validation parameters determined were: linearity, precision, truthfulness (accuracy), limit od detection and quantification.
