Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
Adsorption experiments were conducted by stirring known amounts of Graphene Oxide (GO) or SDS-functionalized Graphene Oxide (GO-SDS) (ranging from 10 to 100 mg) with 25 mL of aqueous Ni (II) solutions (at concentrations ranging from 5 to 40 mg/L) for predetermined time intervals at room temperature (298 K).The concentrations of the Ni (II) solutions were measured by Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES / UNICAM 701 Series Emission Spectrometer) and a UV-Visible spectrophotometer (Cary 100 UV-Vis) by applying the Dimethylglyoxime method . Fourier transform infrared (FTIR) spectra of the samples were recorded with a Varian 800 FTIR spectrometer
