Does the anaerobic formation of hydroxyl radicals by paraquat monocation radicals and hydrogen peroxide require the presence of transition metals?

This in vitro study investigated the formation of hydroxyl radicals (*OH) under anaerobic conditions through the direct reaction between paraquat radicals (PQ(+)*) and hydrogen peroxide (H(2)O(2)) by quantitative UV-VIS and electron spin resonance (ESR) spectroscopy. PQ(+)* was formed by paraquat re...
