Surface Potential of Polycrystalline Hematite in Aqueous Medium
Figure 5
Surface potential of polycrystalline hematite in aqueous NaClO4 solution ( mol dm−3) at 25.0°C. Nonequilibrium data are taken from Figure 3 (♦,▲). Data for partially equilibrated systems (ultrasound) are taken from Figure 4 (◊,∆). Evaluated equilibrium values are denoted with the thick gray band. The solid line was calculated on the basis of the surface complexation model, as demonstrated in the next paragraph. The Nernstian potential is denoted with the dashed line.
