Abstract
The present study aimed to prepare a novel biosorbent of nanochitosan (NCS)/carboxymethyl cellulose (CMC)/graphene oxide (GO) and used to remove Cu(II) ion from wastewater system. The prepared nanocomposite was characterized using FTIR, XRD and SEM analysis. The FTIR and XRD results revealed the formation of novel NCS/CMC/GO nanocomposite. Rough surface morphology of nanocomposite was confirmed from the SEM analysis results. The removal efficiency of Cu(II) ion was evaluated through batch mode by varying pH, adsorbent dose, contact time and initial metal ion concentration. The maximum removal of Cu(II) ion was 80.1% at pH 4, 92.4% at 360 min contact time and about 89.2% for 3 g adsorbent dose. Theoretical models such as Langmuir isotherm, Freundlich isotherm, and kinetics models were used to evaluate the experimental results. After examining, the results revealed that the adsorption follows Freundlich isotherm and pseudo-second-order models. The adsorption capacity of the prepared nanocomposite was 145.22 mg/g.
