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.
