The heats of the immersion of amino, phosphonic and amino phosphonic ion-exchange resins containing different amounts of cobalt or copper ions have been determined with the help of a Calvet microcalorimeter. The adsorption of the water Vapour on phosphonic ion-exchange resin in different ionic forms (H+, Co2+, Cu2+) was studied and enthalpy of the immersion of dry and partially hydrated resins was measured by microcalorimetrical method. The formation of different structures during the water interaction with resin is reflected on the dependence : hydration energy - metal content. The correlation of the Delta H of the immersion and Delta H of the metal ion sorption with the catalytical activity of sorbed complexes of these resins has been shown.
