METHOD AND APPARATUS FOR EFFECTING A CHEMICAL REACTION

摘要

According to the present invention there is provided a method for effecting a chemical transformation, the method comprising the steps of: providing a catalytic substrate; providing a feed comprising one or more reactants; providing an energy source wherein energy derived therefrom is contactable via a transport medium with the catalytic substrate, thereby to provide a species active against said one or more reactants; and contacting the active species with the feed, thereby to actively effect the chemical transformation. Preferably, the active species are free radicals. The catalytic material is preferably TiO<SUB>2</SUB> and the energy is preferably UV light of wavelength 200-400 run. The method is suitable for remediating organic contaminants such as 1,4-dioxane and/or N-nitrosodimethylamine (NDMA), and bacteria, organisms, etc. The present invention also provides an apparatus for performing such a method.
