Evaluations of commercial ion selective electrodes

1. The nitrate ion selective electrode

Research output: Book/ReportReportProfessional

Abstract

Nitrate ion selective electrode, Orion 92-07, was evaluated.Calibration curves were determined in pure potassium nitrate solutions five times with intervals of two weeks.Selectivities with respect to chloride, bromide, iodide, cyanide, hydroxide and sulphate ions were determined by the mixed solution method at four levels of the concentration of the interfering ions. Selectivity coefficients were calculated by the break point method.Morover the pH response was determined.In general, the characteristics were found to confirm the manufacturer's data.
