Data for: Experimental Analysis and Modeling of Closed-Loop Redox Flow Desalination

The data sets give the diluate and concentrate concentration profiles and the cell voltage evolution during the redox flow desalination of aqueous NaCl solution of 3 g/L concentration at the current densities of 3 mA/cm² (DATA SET 1) and 5 mA/cm² (DATA SET 2). The data include: (A) time, t (s) (B) current density, j (A/cm²) (C) experimentally measured diluate concentration, cd_exp (g/L) (D) diluate concentration estimated using the mathematical model, cd_model (g/L) (E) experimentally measured concentrate concentration, cc_exp (g/L) (F) concentrate concentration estimated using the mathematical model, cd_model (g/L) (G) diluate conductivity based on cd_model, sigma_d (S/cm) (H) concentrate conductivity based on cc_model, sigma_c (S/cm) (I) diluate activity coefficient based on cd_model, gamma_d (dimensionless) (J) concentrate activity coefficient based on cc_model, gamma_c (dimensionless) (K) the measured cell voltage, V_exp (V) (L) the voltage drop across the diluate channel, V_d (V) (M) the voltage drop across the concentrate channel, V_c (V) (N) the Donnan potential, V_Donnan (V) (O) other voltage drops, V_other (V), which includes the voltage drops due to the redox reaction and across the ion-exchange membranes (P) the total voltage drop, V_model (V) V_d, V_c, V_Donnan, and V_other are calculated using the mathematical model equations. V_model is the sum of these voltage drops.
