Conductance and effective surface charge density of COC nanochannels after modification by MgCl2 (a) and AlCl3 (b), with different ion concentrations of 0 mM, 10 mM, 100 mM, 500 mM and 1 M. The effective surface charge density values were calculated from Eq. (1). Values in brackets indicate the conductance/surface charge density reduction rate in %. The insets illustrate schematics on the electrostatic interaction between the cations and the negatively charged COC surface.
