This paper deals with the study of the swelling and the sorption properties of new hydrogel networks o f poly (methacrylic acid (MAA)-cross-dodécyle acrylat e ammonium bromide (ADAB). The swelling properties of these hydrogels were achieved in dist illed water at 25°C and expressed by the swelling ratios by weight, in order to evaluate their potent ial applications, particularly in the field of environment. Thus we have tried to take of these sw elling properties by studying the sorption of an industrial dye, in this case, the red dye of bemaci de. Prior to the study of the sorption, study of th e swelling properties has shown a dependence of the s welling rate on the proportion of ADAB included in the hydrogel. The determination of the values of th e capacities of sorption to the aquilibrium of hydrogels enable dus to trace the Freundlich and La ngmuir isotherm and to show that these values are in a good correlation with the Lagmuir isotherm sor ption
