Effects of Iron Ion Ratios on the Synthesis and Adsorption Capacity of the Magnetic Graphene Oxide Nanomaterials
Nanocomposites consisting of graphene oxide (GO) and Fe3O4 nanoparticles are significant structures due to their high absorption and magnetic properties, and they are promising materials for various application areas from drug delivery to dye removal. In this study, the effect of adding iron salts with different Fe2+/Fe3+ ratios during the synthesis of magnetic graphene oxide (MNGO) nanocomposites on size distribution, magnetic properties, morphology, and adsorption–desorption behavior was investigated. Characterization results indicated that superparamagnetic iron oxide nanoparticles (SPIONs) were successfully integrated into MNGO nanocomposites, and the surface area increased when SPIONs were synthesized on GO significantly, especially with increasing Fe2+/Fe3+ ratio. MNGO nanocomposites were tested for the removal of methylene blue (MB). Moreover, the effects of initial pH, dye concentration, and temperature on the adsorption process of MB were also studied. As a result, it is shown that the Fe2+/Fe3+ ratio has a crucial effect on the adsorption–desorption behavior of MNGO nanocomposites, which are promising nanomaterials for dye removal studies.
