Potentiometric method for the determination of nitrate in ill-characterised water

Abstract

ion-selective electrode produces nitrate determination results in good accord with the standard us ,method if one follows recommended procedure and meticulously controlled labotatory conditions.The technique is laborious if different types of ill-characterised water samples are examined in the same series but it is practical and rapid when many samples belonging to same source are to be compared or when continuous monitoring of a water supply with known mineralization is required.
