Abstract
Decomposition tests of hydrazine were conducted in an acidic solution using a hydrogen peroxide solution in a temperature range of 50 to 80 °C. The decomposed fraction of hydrazine was calculated from an analysis of the hydrazine ion concentration in solution by a UV-visible spectrometer. The increase of [Cu2+] increased the decomposition reaction rate of hydrazine. The decomposition reaction rate of hydrazine also increased with the increase of temperature and the solution pH. It was explained that the formation of N2H5+ ion retards the reaction in the lower pH region. One step excess injection of hydrogen peroxide could not decompose the hydrazine efficiently. The decomposed portion of hydrazine could be increased by the repetitive injection of hydrogen peroxide.
