Abstract
The invention relates to methods and processes for the photoassisted oxidation of dissolved species such as arsenic, iron, phosphorous and sulphur. Each aspect of the invention involves supplying to a solution including the species to be oxidized, an oxidant and a photoabsorber, and then irradiating the resultant solution with UV/electromagnetic radiation. The resulting oxidised species can then be subsequently treated, used and/or removed (e.g. through precipation/co-precipitation).
