This study presents the synthesis of activated carbon material by simple thermal treatment of bamboo wood. The synthetic AC shows an amorphous and porous structure. The adsorption of lead ions on synthetic AC was effectuated. The obtained results show that the synthetic AC has a high ability for lead ions removal with high efficiency of 97% after 2 hours of adsorption experiment. The isotherm study showed that lead removal is suitable for both the Langmuir and Freundlich models with a high value of correlation coefficient (R2 = 0.97). The maximum capacity of lead ions removal is high (Qm = 24570 mg/g). Summing up, AC material synthesized from bamboo wood presents a potential material for lead ions removal from the aqueous solution.
