1 Introduction
Hydroxyl radical (HO
• ) is a short-lived free radical, and it is the most potent
oxidizing transient among the reactive oxygen species. It is an effective, nonselective and strong oxidant that is ubiquitously formed in natural sunlit surface waters
(rivers, lakes and seawater and so on), rain, dew, cloud, fog, snow, aerosol, and in
all living organisms. The HO
• is photolytically formed from a variety of sources in
natural waters. The first experimental report of a reaction that is now known to produce HO
• dates back to Henry John Horstman Fenton, who described the oxidation
