A comparative study of electrosorption selectivity of ions by activated carbon electrodes in capacitive deionization

Effect of varying the amount of binder on the electrochemical characteristics of palm shell activated carbon

“…There has been growing interest among researchers to explore the performance of porous electrodes in water and wastewater treatment by means of capacitive deionisation (electrosorption), electro-oxidation and electrodeposition [1][2][3][4][5][6][7][8]. A porous electrode provides a high surface area per unit mass and helps increase the rate of electron transfer [9] as well as the electrochemical active site.…”

Preparation of a manganese dioxide/carbon fiber electrode for electrosorptive removal of copper ions from water

“…Electrosorption is a separation technology combining adsorption and electrochemical methods, used to remove ionic contaminants such as salt ions [1,2], heavy metal ions [3][4][5][6], anions [7], and organics [8,9] from water, and has received extensive attention and support due to its advantages of both waste minimization and reduced processing costs. It has been generally defined as potential-induced adsorption on the surface of charged electrodes.…”

Poly(arylene ether sulfone) copolymers as binders for capacitive deionization activated carbon electrodes

“…Despite activated carbon being widely studied as a material for CDI electrodes (Bouhadana et al, 2011;Choi, 2010;Hou and Huang, 2013;Hou et al, 2012;Huang et al, 2012;Mossad and Zou, 2012;Porada et al, 2012;Villar et al, 2010;Wang et al, 2012;Wang et al, 2013), one of the drawbacks associated with its use is the requirement for a polymeric binder. Typically hydrophobic polymers such as poly(tetrafluoroethylene) (PTFE) (Chang et al, 2012;Lee et al, 2009) or poly(vinylidene fluoride) (PVDF) (Zhang et al, 2012) are used to bind activated carbon powder.…”
