An electrochemical oxidation reactor includes rotatable electrodes inside a reactor vessel. The electrodes are mounted to support plates, which in turn are mounted on shafts. The plates are attached to each other in a spaced relationship so that a gap is formed therebetween. The plates are each electrically insulated from each other. The electrodes are mounted to the inside surfaces of these plates, inside the gap. The gap is sized to receive liquid to be treated so that liquid located within the gap will react with the electrodes. An electrical charge is applied to each shaft so that a dielectric is formed across the gap within the fluid located in the gap. According to a first embodiment, an electrochemical reactor includes containing two spaced electrode support plates. According to another embodiment, an electrochemical reactor includes several spaced electrode support plates.

An asymmetric system containing a first conductive polymer modified with a redox active moiety and a second conductive polymer modified with a surfactant is used for the separation of organic compounds from aqueous solutions. The asymmetric system has complementary hydrophobicity tunability in response to electrochemical modulations. For example, both materials are hydrophobic in their respective neutral states, therefore exhibiting affinity toward organic compounds. Application of a mild potential drives the desorption of the organic compounds and regeneration of the materials. The asymmetric system can be used in a cyclic fashion, through repeated electrical discharge or shorting of the two electrodes to program the capture of organics from a feed solution, and application of a potential to stimulate the release of the adsorbed organics.
