1,4-Dioxane, is a synthetic organic compound used widely throughout industry as a solvent. 1,4-Dioxanecauses liver damage and kidney failure and has been shown to be carcinogenic to animals, and is a potentialcarcinogen to humans. Its recalcitrant nature means that conventional water treatment methods areineffective in removing it from water. A class of technologies called advanced oxidation technologies hasbeen shown to completely mineralise 1,4-dioxane. In this study the effects of pH on TiO2 photocatalysisreactor systems were investigated. pH was found to significantly affect the efficiencies of these processeswith neutral pH conditions the most effective.
