摘要：

The heals of immersion (in water) of outgassed clinoptilolite and its ion-exchanged forms were measured with a Calve calorimeter at 30 degrees C, and the integral heats of sorption were calculated therefrom in order to use zeolites in heating and cooling applications. The immersion and sorption heats were studied as functions of the water saturation degree and the cation contents. The changes observed in the slopes of the sorption curves at low saturation for Ca2+ and Mg2+ ion-exchanged forms were related to the thermal destruction of the heulandite-type structure.
