Developed New Procedure for Low Concentrations of Hydrazine Determination by Spectrophotometry: Hydrazine-Potassium Permanganate System

Abstract

An indirect, sensitive and accurate method for the determination of trace amounts of hydrazine is described. In this proposed the spectrophotometric method is based on its reduction properties of hydrazine with a known concentration of potassium permanganate to reduce the colour. The absorbance of unreduced permanganate is measured the colour difference at different wavelengths 546 and 526 nm which show an absorption spectrum with hydrazine. Hydrazine can be determined in the range of 100 - 700 µg/ml with correlation coefficient of 0.999 and relative standard deviation 1%. The method is successfully applied for the determination of hydrazine in water streams in nuclear reactors/purex process/boiler water and polluted water samples

Phthalhydrazide nanoparticles as new highly reusable organic photocatalyst in the photodegradation of organic and inorganic contaminants

“…Then, the solid photocatalyst was separated by centrifugation and the final solution, involving the in situ generated hydrazine, was exposed to potassium permanganate. The decoloration of permanganate and reduction of Mn(VI) to Mn(II) confirmed the presence of hydrazine . The decrease in the absorbance of permanganate at the wavelengths of 546 and 526 nm was measured (Figure ).…”
