When the swelling reaches a particular extent, the network expansion power became much smaller, and the complexing action of COO− on the resin graft chains with bivalent and trivalent metal cation causes the graft chains that cross-link the resin network structure to shrink (Pourjavadi, Amini- Fazl, & Hosseinzadeh, 2005; Hua & Wang, 2009). This result leads to the leakage of absorbed water; thus, a maximum in swelling with time was observed (Wang & Wang, 2010). The stability constant order of the complexes produced by bivalent and trivalent metal ions with COO− is greater for Ca2+ than in Al3+ because the stability of the complexes formed by bivalent and trivalent metal cations with the resin is much higher than that by monovalent cations (Zhao, Su, Fang, & Tan, 2005). The resin in bivalent and trivalent metal cation solutions exhibits overswelling. The ionic radius of Na+ is smaller than that of Ca2+ and Al3+ at the same plasma strength conditions, and the swelling capacity of the resin in Na+ is higher than in Ca2+ and Al3+. At concentrations from 0.01 mol/L to 0.1 mol/L, the swelling capacity of the resin was highest in NaCl (NaCl > CaCl2 > AlCl3).
