| Research Abstract |
The ion-exchange equilibria of bromide on strongly acidic anion exchange resins (AXR) by mono- and di-carboxylates were analyzed and the variations of selectivity coefficients were explained in terms of hydrophobic interaction between polymer matrix and anions, dehydration, intra- and inter-molecular hydrogen bond formation of anions. Polyacrylates (PA) of low molecular weight penetrated into AXR by ion-exchange mechanism, while those of high molecular weight were adsorbed only on the surface of AXR. In acidic media, PA penetrated into AXRs partly in an acid form. The QCM modified with a cationic polymer showed rapid change in frequency on ion exchange by inorganic ions, but extremely slow response by PA.
