Comparison Of Potentiometric Sensors With Amperometric Sensors For Determination Of Nitrate

A potentiometric sensor based on a membrane-stabilized interface between two immisciblernliquids has been developed. It has been tested in both stationary and flow conditions for therndetermination of nitrate. The selectivity of the sensor based on the concept of ion exchangernhas been studied. On the other hand, an amperometric flowthrough sensor based on nitraterntransfer across the interface of two immiscible electrolyte solutions has been developed. Thernsensor was applied in a flow injection system for the determination of nitrate ion in taprnwater. The results from both sensors (potentiometric and amperometric) are in the samernrange (2.5 - 4.5 mg I"). The results also agreed with measurements conducted using arnUV-detector
