The adsorption of lead (Pb) from aqueous solutions using a wood/nano-manganese oxide composite was investigated to elucidate its mechanism and efficacy. This study explores the synthesis of the composite and its characterization using techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier-transform infrared spectroscopy (FTIR) to assess structural and chemical properties. Adsorption experiments were conducted under controlled conditions to evaluate factors influencing Pb uptake, including pH, initial concentration, and contact time. Results indicate that the wood/nano-manganese oxide composite exhibits significant Pb adsorption capacity, with optimal performance observed at pH [value] and [other relevant conditions]. Isotherm and kinetic models were employed to analyze adsorption behavior, revealing [specific insights into adsorption mechanisms]. Overall, this research contributes to understanding the potential of the wood/nano-manganese oxide composite for efficient Pb removal, offering insights into its application in environmental remediation and water treatment technologies.
