“…Fortunately, the φ-pH diagram for Sn/H2O system can provide the thermodynamic data of the hydrometallurgy. Though the analyzing for the position of Sn species in the φ-pH diagram, the operating conditions of the hydrometallurgy of were optimized [71,72]. Additionally, as shown in Figure 7, the φ-pH diagram for Sn/H2O system provides a theoretical guidance to the Sn electrorefining [73].…”

“…Finally, E-pH diagrams for the Ni-NH3-H2O and Ni-CH3COO --H2O systems were constructed using Equations 25 or 29 for reactions listed in Tables S1 to S4. Nickel is an active metal at acidic pH since the immunity region is located below the water reduction line (line a) [9,39,40]. At low concentration of complexing agents and under acidic conditions, nickel is mostly dissolved as Ni 2+ due to the inability to form a passivation film, and when exposed to highly alkaline solutions, it undergoes dissolution in the form of Ni(OH)3 − .…”

“…Eh-pH diagrams are applicable to aqueous solution systems and reflect the relationship between potential, pH, and ion activity of different reactions under different conditions [23]. The potential-pH diagram shows the equilibrium conditions and stable regions of different components.…”
