Abstract
Adsorption thermodynamics has been studied on the beads of hybrid inorganic ion exchanger: styrene supported zirconium (IV) tungstophosphate for a pes ticide phosphamidon at 30, 45 and 60 degrees C. As a result some thermodyna mic parameters like Freundlich constants, thermodynamic equilibrium constan t (K-0), standard free energy changes (Delta G(0)), standard enthalpy chang e (Delta H-0) and standard entropy changes (Delta S-0) have been evaluated.
