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.
Key words: Diffusion coefficient, NaCl, acrylamide, hydrogels.
