In situ techniques have attracted great attention for the formation of nanomaterials with controlled sizes, shapes and dispersion within supramolecular hydrogels. In the present work, the doping of copper oxides onto magnetite nanoparticles into hydrogels based on sodium 2‐acylamido‐2‐methylpropanesulfonate (AMPS) and N ‐isopropylacrylamide NIPAm copolymers was investigated. The contents, morphology and thermal stability of magnetite, cupreous oxide and doped copper oxides onto the magnetite nanoparticles were evaluated. The optimum conditions for removal the cationic dye methylene blue (MB), such as solution pH, concentration of adsorbents, contact time and stirring time, were determined to investigate the effect of MB concentrations on the removal efficiencies of the prepared adsorbents. The recyclability of the prepared AMPS/NIPAm composites for the removal of MB was examined for up to six cycles without changes in removal effectiveness. © 2018 Society of Chemical Industry
