ISOMERIZATION AND DISSOCIATION OF THE PEROXYNITRITE ION FORMED BY DISSOLVING CRYSTALLINE POTASSIUM NITRATE IRRADIATED WITH 253.7 NMLIGHT

Abstract

Photoinduced peroxynitrite in potassium nitrate is stable after dissolution in highly alkaline solutions (pH > 13). Increasing the pH of the solution from 10.5 to 14 increases peroxynitrite stability. Dissolution of the samples in the pH range of 3 – 14 results in varying the degrees of peroxynitrite, and in the pH range of 6 ~ 13.5 peroxynitrite undergoes dissociation to form nitrite with different yield.
