“…The salt adsorption capacity (SAC) was calculated using eqn (5). 33 where C o , C e , V and m are the initial salt concentration (mg L −1 ), equilibrium salt concentration (mg L −1 ), total volume of salt solution (L) and combined mass of SRGO–MnO 2 and SRGO on both sponges (g). The salt adsorption rate (SAR) was calculated using eqn (6).where t is the time needed to attain the equilibrium salt concentration (s).…”
Capacitive deionization (CDI) has emerged as low-cost, reagent-free technique for desalination of water. The technique is based on immobilization of dissolved ions on the electrically charged electrodes, by the electrosorption...

“… 15 Electrochemical analysis of camphor carbon fume by cyclic voltammetry with constant current charge-discharge showed that the doping of nitrogen significantly increased its specific capacitance and caused it to exhibit multilayer adsorption on non-homogeneous surfaces following Freundlich. 16 As another efficient adsorption material, multiwall carbon nanotubes can improve the stability of emulsion liquid membrane (ELM) by approximately 20% when effectively applied, reduce the swelling ratio of emulsion by 42%, and increase the mass transfer coefficient by 4.746% when cooperating with surfactants. 17 , 18 On the other hand, this saturated adsorption device enriched with many charges is often regarded as an energy storage device.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
