The present work deals with the influence of temperature on the ion-exchange capacity of selected ion-exchangers. Technological operations running at elevated temperatures (drying, homogenization) can influence the lead or ion-exchange capability of ion-exchangers, which may affect values of the ion-exchange capacity. Several types of anion and cation-exchangers have been chosen for its application in practice. Samples of selected ion-exchangers were subjected to thermal stress in the temperature range of 75-160°C at different times of exposure. It was shown that the optimum processing temperature for anion and cation-exchange resins is in the range of 105-115°C.
