Ion Chromatography (IC) as a Method in Studies on the Odra River Pollution with F-, Cl-, NO3-, PO43-, SO42- Ions

Abstract

The paper presents the ion chromatography (IC) DIONEX DX-100 system -- in the studies on the Odra River water pollution with some inorganic anions. The precision of analysis, detection and quantification limits of each anion have been presented in order to evaluate the method. Results obtained with IC are compared with those using other analytical methods: ICP-AES for SO 2- 4 , and the argentometric titration for Cl - , It has been found that the IC method can be applied in the investigation of the anion pollution of the Odra River water: concentrations of Cl - , NO - 3 and SO 2- 4 can be determined with sufficient accuracy, while F concentration, on the account of common presence of carbonate anions, can only be roughly estimated. The results have been compared with maximum permitted levels (MPL) for Polish water quality classes.
