In this work a model based on a monophasic approach will be used to describe a general behavior of anionic hydrogels in a steady state condition at pH lower (or equal) to seven. Free swelling experiments and constrained swelling experiments have been simulated varying the parameters of the model to highlight the properties of the material.
