A kind of Hofmeister Series for hydrogel swelling was investigated with a special attention to ion effects on the hydrogen-bonding hydration at polar groups on polymer. On the basis of experimental observations for several polymer gels, we proposed a model mechanism for the ion-specific gel swelling. According to the model, the hydrogen-bonding hydration on the polar groups is stabilized or destabilized by ions through ionic hydration since anion and cation change water s abilities for electron pair donation (EPD) and acceptance (EPA), respectively.
