Hydroxyl radicals may be used as disinfection agent in the advanced oxidation processes or tertiary treatment of waste and occasionally drinking water. We very recently oxidised a gram negative bacterial cell wall proxy at the liquid-solid interface with aqueous hydroxyl radical, the experiment (RB1820244) was a complete success and is being written up as a letter for publication. Our previous exploratory work, demonstrated the polysaccharides are an effective layer to resist oxidative attack, but did...
