(color online) Comparison between surface potentials obtained from this study and the GC model for negatively charged particles with different charge densities in 2:2 + 2:1 mixed electrolyte solutions, for fC = 0.001 mol·L−1 (a), 0.01 mol·L−1 (b), and 0.1 mol·L−1 (c). The lines are calculated from this study considering dielectric decrement, and the symbols denote values estimated from the GC model.
