摘要：

The thermodynamics of the adsorption of phosphamidon on antimony(V) phosphate cation exchanger has been studied at 30, 45 and 60-degrees-C and the thermodynamic equilibrium constant (K0), standard free energy change (DELTAG-degrees), enthalpy change (DELTAH-degrees) and entropy change (DELTAS-degrees) have been calculated to predict its adsorption behaviour. All the data are adequately represented by the Freundlich isotherms.
