摘要

The absorption spectrum of the hypochlorite ion (arncomponent of free chlorine) overlaps the ultraviolet (UV)rnend of the solar spectrum. This suggests that solar lightrncan possibly initiate the UV/chlorine advanced oxidationrnprocess as a replacement for processes driven by UV lightrnfrom UV lamps. In this study, the solar drivenrnUV/chlorine advanced oxidation process was assessed byrnthe determination of the quantum yield at 303 nm ofrnactive chlorine at pH 10 and the measurement of the yieldrnfactor. This treatment was successfully applied to therndegradation of methylene blue (MB), which is a modelrncompound for organic dyes. Photobleaching MB wasrnobserved in bench scale experiments. A future goal of thisrnproject is to apply this treatment to cyclohexanoic acidrn(CHA), which is a model compound of the toxicrnnaphthenic acids found in typical oil sands process waterrn(OSPW).
