Description

The biocides produced by the reaction between hydrogen peroxide ( H₂O₂ ) and nitrite ( NO₂⁻ ) upon addition of acid are already known from the literature. Furthermore, it is known from the literature that various reaction species, including peroxynitrite (ONOOH) and its acid residual ion peroxynitrite ( ONOO⁻ ), nitric oxide (NO), nitrogen dioxide ( NO₂ ), hydroxyl radical (OH), and hydroperoxyl radical ( HO₂ ), are formed by this reaction (Figure 1). Peroxynitrite , in particular, is considered a potent biocide in the literature, but its extremely short lifespan of only 0.8 seconds presents a problem for its use as a disinfectant, as a minimum period of action is required to kill a sufficient number of pathogens.
