Identification and Removal of the Main Interferences

Inorganic and organic interferences were investigated with respect to the determination of bromate in natural and drinking waters by an ion chromatographic method (Guinamant et al, 2000 Ingrand et al, 2002). The tested interferenees were of two types  

These experiments demonstrated an important analytical feature, namely that bromate analysis cannot be performed directly for waters containing more than 50 mg/L of bicarbonate and 10 mg/L of chloride (which correspond to levels commonly found in natural waters), and that consequently a pre-treatment step is required. These results were confirmed by the analysis of natural river and mineral waters (Ingrand et al, 2002).
