An ion-exchange membrane is a semi-permeable membrane that transports certain dissolved ions, while blocking other ions or neutral molecules. [1] Ion-exchange membranes are therefore electrically conductive. They are often used in desalination and chemical recovery applications, moving ions from one solution to another with little passage of ...
Energy Exploration Technologies, Inc. (more commonly known as EnergyX) is an American technology company. [1] Founded in 2018 by Teague Egan, it is based out of San Juan, Puerto Rico and has offices and laboratory facilities in Austin, Texas, [2] and operations in the South American Lithium Triangle (Bolivia, Chile and Argentina).
By inserting two ion exchange membranes, a modified form of CDI is obtained, namely Membrane Capacitive Deionization. [13] This modification improves the CDI cell in several ways: Co-ions do not leave the electrodes during the adsorption phase, as described above (see Ion adsorption in Electrical Double Layers for explanation).
Compared to RO membranes, ion exchange requires repetitive regeneration when inlet water is hard (has high mineral content). [citation needed] Industrial and analytical ion-exchange chromatography is another area to be mentioned. Ion-exchange chromatography is a chromatographical method that is widely used for chemical analysis and separation ...
Electrodeionization (EDI) is a water treatment technology that utilizes DC power, ion exchange membranes, and ion exchange resin to deionize water. EDI is typically employed as a polishing treatment following reverse osmosis (RO), and is used in the production of ultrapure water. It differs from other RO polishing methods, like chemically ...
Like a proton-exchange membrane (PEM), the membrane separates the products, provides electrical insulation between electrodes, and conducts ions. Unlike PEM, AEM conducts hydroxide ions. The major advantage of AEM water electrolysis is that a high-cost noble metal catalyst is not required, low-cost transition metal catalyst can be used instead ...
Early proton-exchange membrane technology was developed in the early 1960s by Leonard Niedrach and Thomas Grubb, chemists working for the General Electric Company. [6] Significant government resources were devoted to the study and development of these membranes for use in NASA's Project Gemini spaceflight program. [ 7 ]
Poly(fluorenyl-co-aryl piperidinium) (PFAP)-based anion exchange materials (electrolyte membrane and electrode binder) with high ion conductivity and durability under alkaline conditions has been demonstrated for use to extract hydrogen from water. Performance was 7.68 A/cm 2 at 2 V, some 6x the performance of existing materials.
