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.
