ABSTRACT = {A novel magnetic hydrogel loaded with graphene oxide (GO) was developed in this study. Firstly, GO was prepared from bagasse through a single step via oxidation in the presence of ferrocene under muffled atmospheric
conditions, followed by the loading of different amounts of magnetite onto GO via co-precipitation reaction of
iron onto GO sheets. Finally, the 2-acrylamido-2-methyl-1-propane sulfonic acid was grafted onto carboxymethyl
cellulose in the presence of magnetite GO and N, N′-methylenebisacrylamide as crosslinker yielded hydrogel. The
structure, morphological, and thermal behavior of the prepared hydrogels were investigated. In addition, the
adsorption performance of Ni(II) ions from aqueous media by the prepared hydrogels was investigated as a function of temperature, time, and concentration of adsorbate in a batch system. The results demonstrated a remarkable enhancement in the adsorption process of Ni(II) (Removal efficiency = 98.82%). All isotherms were found to
fit the Langmuir model best. The adsorption properties of both magnetic GO and magnetic hydrogel showed
promising properties as green and cheap adsorbents.},
