In this study, chitosan–metal oxide composites (CS–MO) were prepared for graphene oxide (GO) removal from aqueous solutions. The results showed that the GO coagulation on CS–MO was dependent on pH and ionic strength. The maximum GO removal capacities reached 442.5 mg/g on CS–Al2O3, 425.0 mg/g on CS–ZnO and 421.2 mg/g on CS–MgO, respectively, showing a huge advantage in the efficient elimination of...
In this work, a carboxymethyl cellulose (CMC)-modified Fe3O4 (denoted as Fe3O4@CMC) composite was synthesized via a simple co-precipitation approach. Fourier transform infrared spectroscopy, zeta potential and thermogravimetric analysis results indicated that CMC was successfully coated on the Fe3O4 surfaces with a weight percent of ~30 % (w/w). The prepared Fe3O4@CMC composite was stable in acidic...
