Evaluating the absorption coefficient of NaCl in hydrogels acrylamide

Abstract

In this study, acrylamide hydrogels with different amounts of water in the initial reaction mixture were
synthesized. NaCl absorption capacity was determined by the hydrogels. It was found that the acrylamide
hydrogels are nonselective absorption of chlorine ions or sodium. However, similar solute concentrations
inside and outside of the hydrogel were obtained. The diffusion coefficients were determined when the
hydrogels were placed in bidistilled water and in aqueous solutions at 50 and 100% saturation.
