Ion chromatography (IC) as a method in studies on the Odra river pollutionwith F-, Cl-, NO3-, PO43-, SO42- ions

The paper presents the ion chromatography (IC)-DIONEX DX-100 system - in th e studies on the Odra River water pollution with some inorganic anions. The precision of analysis, detection and quantification limits of each anion h ave been presented in order to evaluate the method. Results obtained with I C are compared with those using other analytical methods: ICP-AES for SO42- , and the argentometric titration for Cl-. It has been found that the IC me thod can be applied in the investigation of the anion pollution of the Odra River water: concentrations of Cl-, NO3- and SO42- can be determined with sufficient accuracy, while F- concentration, an the account of common prese nce of carbonate anions, can only be roughly estimated. The results have be en compared with maximum permitted levels (MPL) for Polish water quality cl asses.
