There have been many products tried and tested in the realm of hospital and healthcare in the quest to discover the most effective cleaner in an industry where hygiene is paramount. Peracetic acid (PAA) is increasingly used as an alternative disinfectant and its advanced oxidation processes (AOPs) could be useful for pollutant degradation. It can be highly corrosive. Peracetic acid (PAA) with the empirical formula CH3COOOH is strong oxidizing agent as a selective agent of delignification. It is an oxidizing biocide that degrades relatively quickly into non-toxic by-products. Peracetic acid is a weaker acid than the parent acetic acid, with a pK a of 8.2. A liquid that functions as a strong oxidizing agent. The more concentrated the Peracetic acid solution, the more effective it is as an antimicrobial, but the greater the vapor concentration and so the greater the exposure risk to everyone around. Co(II) or Co(III) can activate PAA to produce acetyloxyl (CH3C(O)O•) and acetylperoxyl (CH3C(O)OO•) radicals with little •OH radical formation, and Co(II)/Co(III) is cycled.
