Colloidal stability and heavy metal adsorption on rGO, rGO/magnetite, rGO/silver, and rGO/magnetite/silver

Description

The data set shows 1) adsorption kinetics and capacities for Cd(II), Ni(II), Zn(II), Co(II), Pb(II), and Cu(II) as affected by pH and ionic strength; 2) hydrodynamic diameter of nanomaterials as a function of time; and 3) X-ray photoelectron spectra (XPS) of rGO before and after Cd(II) adsorption; and (4) X-ray diffractograms (XRD) of nanomaterials. This dataset is associated with the following publication: Park, C.M., D. Wang, J. Han, J. Heo, and C. Su. Evaluation of the colloidal stability and adsorption performance of reduced graphene oxide–elemental silver/magnetite nanohybrids for selected toxic heavy metals in aqueous solutions. Applied Surface Science. Elsevier B.V., Amsterdam, NETHERLANDS, 471: 8-17, (2019).
