Abstract
Nitratcs were determined in mineral water by standard addition and standard curve with the selective potentiometric electrode. The results were
compared with those obtained by the tech n ique of reduction in cadmium-column. The interference of chloride ions in the potentiometric methcd was also studied. The comparison showed similar resul ts of both methods but the selective electrode procedure seems to be more appropriate for routine determinations.
