Abstract

Kakovost vode odraža sestavo vode, odvisno od naravnih procesov in aktivnosti človeka, kar določamo s kvalitativno in kvantitativno oceno. Parametri, ki opisujejo kvaliteto vode, so odvisni od namena uporabe vode. Za vsako nameravano uporabo vode obstaja skupina parametrov, ki najustrezneje izražajo kakovost. Vsebnost določenih anionov, kot so na primer klorid, nitrat (V), sulfat, fosfat in nitrat (III) je pokazatelj kakovosti vode. Diplomsko delo obsega določanje koncentracije anionov z ionsko kromatografijo in primerjavo določanja koncentracije fosfata z ionsko kromatografijo in molekulsko spektroskopijo. Po optimizaciji analiznega postopka smo izvedli validacijo analizne metode. Potrdili smo, da so rezultati meritev natančni in točni ter da je metoda primerna za določanje vsebnosti anionov v različnih vrstah vod.

Secondary title:	DETERMINATION OF ANIONS BY ION CHROMATOGRAPHY
Secondary abstract:	Water quality is reflecting in the content of different compounds, depending on natural processes and human activities, as well. It can be determined by qualitative and quantitative estimation. Parameters which represent water quality are dependent on intention of water use. For every type of water usage there are different parameters which describe water quality in most adequate way. Content of certain anions such as chloride, nitrate (V), sulfate, phosphate and nitrate (III) is an indicator of water quality. Thesis comprises the determination of anions using ion chromatography and comparison of two methods, namely molecular spectroscopy and ion chromatography for phosphate determination. After analytical procedure optimisation, the validation of analytical method was performed. Results of measuements are precise and accurate and it is proved that the method is suitable for anion determination in different types of water.
