In this work, carbon based cellulose was composites with manganese oxide for lithium recovery. From the results, it was found that steam activation was observed to have an influence on the development of pores and the effective pore size for lithium adsorption on the carbon surface. The amount of lithium ion recovery was enhanced by basic treatments and we characterized lithium ion adsorption-desorption efficiency. The structure and morphology of composite were examined by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS). The specific surface area of the composites was calculated from N2/77k adsorption/desorption isotherms by the Brunauer-Emmett-Teller (BET) equation. Adsorption-desorption capacities of lithium ion were examined by AAS (AA-SCANI; Thermo Jarrell Ash Co.). |
