Abstract :

The article presents a modified method in which NO is oxidized quantitatively to NO2 by chromium trioxide (CrO3), before conversion to NO2u and NO3u in an alkaline hydrogen peroxide (H2O2) solution. A denitrifier method is used to reduce NO2u and NO3u in the trapping solution quantitatively to nitrous oxide (N2O) for subsequent 15N analysis. In a soil incubation experiment with 15NH4NO3, NH415NO3, or Na15NO2 amendments, it is found distinct 15N abundances in NO, indicating that the method is well suited to investigate NO sources in soils.
