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… More >
