The weight ratios controllable synthesis of novel and effective RGO-Nix/MnO2y nanocomposites was done by hydrothermal approach. The reduction of graphite to graphene oxide, fabrication of MnO2 and deposition of Ni-MnO2 above the surface of reduced graphene oxide was individually carried out by hydrothermal technique. The physical and morphological properties of prepared nanocomposites was analyzed. The batch adsorption experiment was performed to identify the lithium uptake capability of nanomaterials, in this study following parameters optimized to enhance adsorption rate; including effect of pH, dosage, contact time, and preliminary Li+ solution concentrations. The various kinetics and equilibrium isothermal models applied on experimental data to identify the nature of adsorption phenomena. To make process more economic and efficient, the Li+ desorption experiment performed. Briefly, it can be concluded that the prepared nanocomposites possessed adequate potential for lithium uptake. |
