A portable electrolytic water purifier includes a housing, a base, a first conducting grid plate, a second conducting grid plate and an electrolytic circuit module. The housing has a container coupling portion. The base is mounted inside the housing and has an assembly ring connected with the container coupling portion. The second and first conducting grid plates are respectively mounted inside the assembly ring, are overlapped in a top-down manner, and are located under an opening of the container coupling portion. The electrolytic circuit module is mounted inside the housing and is electrically connected to the first and second conducting grid plates. After a container filled with water is inversely placed on the water purifier, the first and second conducting grid plates are immersed in water to decompose the water into electrolyzed water through electrolysis.

A metal ion generator for fluids includes a pipe having an insertion aperture positioned between the fluid inlet and fluid exit, and a conductive member configured to be removably secured in the insertion aperture. The conductive member includes a rigid non-conductive extension and a metal bar. When secured in the insertion aperture, the rigid non-conductive extension positions the metal bar into the direct flow of fluid between the fluid inlet and the fluid exit. A power source applies a voltage to the conductive member causing the metal bar to function as an anode and generate metal ions that are transferred into the fluid. The power supply also connects to a cathode such as the pipe or a second conductive member secured in the insertion aperture.

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.
