Fig. 4: Anodic potentiostatic current evolution of iron in different bentonite slurries.
From: Anodic dissolution mechanisms of iron in bentonite slurries

Evolution of the current densities measured during anodic potentiostatic tests (Eapplied = −0.4 VAg/AgCl) for 20 mins, in bentonite slurries of different concentrations: 1.6% slurry (black line), 3.2% slurry (red line), 6.3% slurry (blue line), 9.1% slurry (magenta line). Fine lines indicate the replications.
