Capacitive deionization (CDI) is an emerging water desalination technology for removing different ionic species from water, which based on electric charge compensation by these charged species. CDI becoming popular because it more energy-efficient and cost-effective than other technologies, such as reverse osmosis distillation, specifically in dealing with brackish having low or moderate salt c...

Ion transport in porous conductive materials is of great importance in a variety of electrochemical systems including batteries and supercapacitors. We here analyze the coupling of flow and charge transport and charge capacitance in capacitive deionization (CDI). In CDI, a pair of porous carbon electrodes is employed to electrostatically retain and remove ionic species from aqueous solutions. W...

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...

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 ...

Today, one of the most important issues all is supply drinking and utility water, which basic need for human beings, to be healthy reliable, economical. Some substances in natural water sources pose a danger living creatures when they exceed certain concentrations. Fluoride, can commonly found as result or industrial effects, poses various risks not only its deficiency, but also excess. Therefo...
