Figure 2: Spontaneous desalting by CICP.
From: Capillarity ion concentration polarization as spontaneous desalting mechanism
A fluorescent signal tracking through the microchannel with different compositions of the ionic hydrogel, (a) HEMA: AA=5:1 in the centre-connection device, (b) HEMA: AA=5:1 and (c) HEMA: AA=5:3 in the end-connection device. The plots of normalized concentration inside the ion-depletion zone with fixed (d) Pe at 0.1 and (e) ionic flux at 0.1.
