Fig. 4: Effect of activated carbon loading and initial pH on arsenic removal.

From: Symmetric anion exchange membranes enhance arsenic removal and overcome conductivity limitations in FCDI systems

Fig. 4

a The effect of activated carbon mass fraction (3, 6, and 9 weight percent) in the flow-electrode suspension on the arsenic removal efficiency over 240 min. b The effect of initial feed water pH (adjusted to 3, 5, 7, and 9) on the arsenic removal efficiency. Data points represent the mean ± SD from n = 3 independent experiments.
