Salt-free softening by thermo-reversible ion-adsorbing hydrogels

Salt-free softening by thermo-reversible ion-adsorbing hydrogels

ABSTRACT In this article, we demonstrate the properties of a hydrogel capable of adsorbing calcium cations from aqueous streams at ambient temperatures (10–25°C) and showing almost complete desorption of the bound calcium ions at slightly elevated temperatures (40–50°C). Successful breakthrough expe...

Zusammenfassung:ABSTRACT In this article, we demonstrate the properties of a hydrogel capable of adsorbing calcium cations from aqueous streams at ambient temperatures (10–25°C) and showing almost complete desorption of the bound calcium ions at slightly elevated temperatures (40–50°C). Successful breakthrough experiments in a fixed bed column set‐up show the potential of the hydrogel in softening water streams from 150 ppm toward
