The scattered plots of the Maxwell current density and the total ion concentration variations (mobility >0.77−0.97 × 10−4 cm2 V−1 s−1; diameter < 1.45–130 nm) with the potential gradient for the two groups. The correlation coefficient (R) with the standard deviation (SD) and the physical significance level (P) are given in each case.
