Abstract: A new viewpoint on metal complex system was proposed on traditional M-ligand-H2O system φ- pH diagrams. Simultaneous equilibrium principle and activity term method were used to plot all-equilibrium φ- pH diagrams for M-ligand-H2O systems based on the thermochemical database developed. The mathematical and computer algorithms were described with the Cu-NH3-H2O system as an example. More quantitative information on real hydrometallurgical processes can be obtained from these diagrams compared with the conventional Pourbaix φ- pH diagram.
