Water desalination using capacitive deionization with microporous carbon electrodes.
Capacitive deionization (CDI) is a water desalination technology in which salt ions are removed from brackish water by flowing through a spacer channel with porous electrodes on each side. Upon applying a voltage difference between the two electrodes, cations move to and are accumulated in electrostatic double layers inside the negatively charged cathode and the anions are removed by the positi...
متن کاملEffective Modified Carbon Nanofibers as Electrodes for Capacitive Deionization Process
Carbon materials have the advantages of good electrical conductivity and excellent chemical stability, so many carbon materials have been introduced as electrodes for the capacitive deionization (CDI) process. Due to the low surface area compared to the other nanocarbonaceous materials, CNFs performance as electrode in the CDI units is comparatively low. This problem has been overcome by prepar...
متن کاملUsing Mesoporous Carbon Electrodes for Capacitive Deionization (CDI) of Salt and Brackish Water
Capacitive Deionization [2] (CDI [3]) is a water [4] purification process that offers promise in the deionization of salt and brackish water [4]. The process can create potable water [4] out of salt laden water [4] by using electric currents to separate the ions in the solution and attract them to cathode and anode plates. These plates act as filters, drawing salt and other ionized metals out o...
متن کاملAttractive forces in microporous carbon electrodes for capacitive deionization
The recently developed modified Donnan (mD) model provides a simple and useful description of the electrical double layer in microporous carbon electrodes, suitable for incorporation in porous electrode theory. By postulating an attractive excess chemical potential for each ion in the micropores that is inversely proportional to the total ion concentration, we show that experimental data for ca...
متن کاملEnhanced capacitive deionization of graphene/mesoporous carbon composites.
Capacitive deionization (CDI) with low-energy consumption and no secondary waste is emerging as a novel desalination technology. Graphene/mesoporous carbon (GE/MC) composites have been prepared via a direct triblock-copolymer-templating method and used as CDI electrodes for the first time. The influences of GE content on the textural properties and electrochemical performance were studied. The ...
