Abstract
A photoreactor including a reservoir configured to hold water, the reservoir defining an inlet and an outlet, and a multiplicity of optical fiber assemblies positioned in the reservoir. Each optical fiber assembly includes one or more optical fibers coated with a composition comprising a photoresponsive polymer and a light source optically coupled to the one or more optical fibers. The photoresponsive polymer undergoes a change from an initial state to an irradiated state when irradiated with light from the light source, and photoresponsive polymer in the irradiated state is adapted to bind an ion from the water.
