Deionization shocks in microstructures.
Salt transport in bulk electrolytes is limited by diffusion and advection, but in microstructures with charged surfaces (e.g., microfluidic devices, porous media, soils, or biological tissues) surface conduction and electro-osmotic flow also contribute to ionic fluxes. For small applied voltages, these effects lead to well known linear electrokinetic phenomena. In this paper, we predict some su...
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 کاملA Comparative Study between Membrane Capacitive Deionization and Capacitive Deionization from Isotherms and Kinetics
Membrane capacitive deionization (MCDI) is a promising technique to achieve the desalination. This novel technique can largely improve the desalination efficiency of capacitive deionization (CDI) by introducing ion-exchange membranes into CDI. This paper presents a comparative study on the electrosorptive performances of CDI and MCDI based on single walled carbon nanotubes electrodes in NaCl so...
متن کاملEnergy breakdown in capacitive deionization.
We explored the energy loss mechanisms in capacitive deionization (CDI). We hypothesize that resistive and parasitic losses are two main sources of energy losses. We measured contribution from each loss mechanism in water desalination with constant current (CC) charge/discharge cycling. Resistive energy loss is expected to dominate in high current charging cases, as it increases approximately l...
متن کاملTwo-Dimensional Porous Electrode Model for Capacitive Deionization
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...
