Abstract

This work is aimed at studying HNO2 generation by bubbling NO in HNO3 solution. The formation and decomposition of HNO2 depend on the 2NO+HNO3+H2O⇄3HNO2 reaction. During the HNO2 generation, the HNO3 concentration was kept constant. The influence of HNO3 concentration, temperature, NaNO3 concentration and NO bubbling rate was studied. Its possible application in the PUREX process was evaluated.
