摘要: We describe a simple and inexpensive cellulose-derived layer-by-layer stacked carbon fiber network electrode for capacitive deionization (CDI) of brackish water. The microstructure chemical composition were characterized using spectroscopic microscopic techniques; electrochemical/electrical performance was evaluated by cyclic voltammetry 4-probe electrical conductivity surface area Brunauer–Emmett–Teller analysis, respectively. desalination investigated laboratory batch model CDI unit, under fixed applied voltage varying salt concentrations. Electro-adsorption NaCl on the graphite reinforced-cellulose (GrC) reached equilibrium quickly (within 90 min) adsorbed salts released swiftly (in 40 back into solution, during reversal potential. X-ray photoelectron studies clearly illustrate that sodium chloride ions physisorbed negative positive electrodes, respectively elect...
