چکیده    In this study, acrylamide based graft poly (acrylic acid) hydrogel (am-g-p(ac)) and its nanocomposite with cds nanoparticles am-g-p(ac)/cds were produced by the free radical method and utilized for methylene blue (mb) dye removal from aqueous solution. the characterization and properties of the adsorbents were studied utilizing fesem, ftir, tga, and xrd analyses, and the results showed that cds nps were successfully distributed in the hydrogel structure. cds nps were loaded into the hydrogel system and the best adsorption capacity of mb dye was determined at 0.05 g of cds nps. also, the effect of equilibrium time, initial concentration, temperature, and initial ph on the adsorption capacity of mb dye was studied. behavior of the equilibrium investigation of the adsorption method show that the equilibrium result determined are in the best agreement with the freundlich isotherm model and the multilayer surfaces play an effective role in the adsorption method. the best multilayer adsorption efficiency (qmax) determined utilizing isotherm freundlich model for am-g-p(ac)/cds. the maximum adsorption capacity (qe mg/g) determined for cmc-g-p(aam) and am-g-p(ac)/cds were determined as 534.45 mg/g and 467.67 mg/g, respectively. the biological compound activity results were observed before and after the process of loading cds nps on it against the types of bacteria tested (staphylococcus epidermidi and staphylococcus aureus) and (e. coli and klebsiella spp.).
