Abstract
The research study reports a fresh synthesis of clay-biochar nanocomposite material derived from natural clay and Prosopis Juliflora plant for effective removal of lead metal from aqueous solution. The nanocomposite material was formed by heat pyrolysis of clay and biochar biomass at different temperatures and synthesis was confirmed by characterization with XRF, EDX, FTIR, XRD, and SEM. The characterization revealed successful impregnation of the clay minerals on the surfaces of the biochar material to form the composite material. The efficacy of removal of lead metal by the composite material was ascertained by the batch adsorption method. The three materials of calcined clay, biochar, and composite material all produced a good removal efficacy. Adsorption isotherms of Frendluich and Langmuir to study adsorption were used which showed near to fit adsorption isotherms for lead removal from aqueous solution. The data also showed a pseudo-second-order reaction for the removal of lead metal.
