| 英文摘要 | A given metal ion can form various adsorption states with different energies on inorganic mineral surfaces under the same conditions of temperature, pressure, pH and ionic strength. For example, hydrated zinc ions were adsorbed onto manganite surfaces in two different modes of corner-linkage and edge-linkage. Surface adsorption reactions were generally terminated in various metastable equilibrium adsorption (MEA) states rather than a unique ideal equilibrium state that was predicted from the classical adsorption thermodynamics. Based on the MEA inequality of the MEA theory, we deducted the thermodynamic relationships between the real equilibrium adsorption constant (K-real) and the metastable-equilibrium coefficient (K-me). It showed that K-me is exponentially related to the energy difference between different MEA states. By affecting MEA states, kinetic factors, such as reactant concentrations, can fundamentally influence the real equilibrium adsorption constants and other thermodynamic properties such as adsorption isotherms. |
