Abstract

The poly(vinyl alcohol) (PVA) and alginate hydrogels crosslinked at pH >9 with sodium tetrahydroxyborate (PVA-Bb) hydrogels are shape-stable under repeated dry–rewet cycles. Further crosslinking with sulfate ions to substitute the involved borate complex (PVA-Sb) only moderately enhanced the hydrogel stability. The B(OH)₄⁻ cores constitute the skeleton of the PVA-Bb matrix under alkaline condition, which is different from the B(OH)₃ cores that are noted principally constituting the hydrogel matrix formed under acidic condition. The shape-stable PVA-Bb Prussian blue (PB) immobilized hydrogels are effective adsorbent of Cs⁺ ions from waters. The Cs⁺ permeabilities for PVA-Bb and PVA-Sb hydrogels are close.
