Sažetak
The non – suppresed Ion Chromatographic method with conductometric detection is described for simultanious determination of six inorganic anions: fluoride, chloride, nitrite, bromide, nitrate and sulphate. The separation was achived on a low capacity anion exchange column Metrohm IC Anion Column Super Sep, with a mobile phase consisted of phtalic acid dissolved in high puriti water, 2-amino-2-hidroxymethyl-1, 3-propendiol and acetonitrile. The purpose of this work is to characterize the method in order to be applied to the routine analysis of drinking water. In this work computer optimization procedures, using computer programs to select chromatographic conditions have been used, leading to the achievement of a desired separation. By using the different optimization methods in an integrated manner it is, however, possible both to speed method development, by reducing unnecessary experimentation, and to overcome many of shortcomings of each method, because the different approaches. The validaty of the method was established by intra - day and inter day calibration studies, precision and accuracy, sensitivity, detection limits and working range and detectibility.
