摘要：

Decomposition of ammonium nitrate in the HNO3-HCOOH system was studied in the presence or absence of Pt/SiO2 catalyst. It was found that decomposition of ammonium nitrate is due to homogeneous noncatalytic oxidation of ammonium ion with nitrous acid generated in the HNO3-HCOOH system during denitration. The platinum catalyst initiates the reaction of HNO3 with HCOOH to form HNO2. The regular trends were revealed and the optimal conditions of decomposition of ammonium nitrate in nitric acid solutions were found.
