Abstract
Abstract A rapid method has been established for determination of mixtures of hydrazine and hydroxylamine by potentiometric titration using an iodide ion-selective electrode. Accurate values are obtainable when nitric acid is added to the sample solution. A recommended procedure is proposed in which the sum of hydrazine and hydroxylamine is titrated with an aliquot of sample solution and another aliquot is titrated to the end point for hydrazine after hydroxylamine has been decomposed with nitric acid. Hydrazine and hydroxylamine in mixture can be determined in the concentration range of 0.01–0.5 mmol/dm3. The best result, with relative error and relative standard deviation both of less than 0.7%, may be obtained on 0.5 mmol/dm3 hydrazine and hydroxylamine.
