Abstract

In this work, we studied the release of nitrogen oxides (N2O, NO and NO2) during UN dissolution at different concentrations of HNO3 (3–16 mol l−1) at a ratio between the solid (S) and liquid (L) phases of 1:7.5 (w/w), as well as at an HNO3 concentration of 7.2 mol l−1. and L:S ratios from 3 to 30 (w/w). The UN amounts were varied from 50 to 500 mg. The experiments were carried out at a temperature of 50–60 °C in the air or argon atmosphere.
