Using X-ray photoelectron spectroscopy and FTIR analysis to determine the elemental composition and surface functional groups of the activated carbon surface, the presence of oxygen-related functional groups was observed. The maximum adsorption capacities were 135.8 mg g<sup>-1</sup> and 31.0 mg g<sup>-1</sup> for removal of lead and copper solutions with the initial concentration of 300 mg L<sup>-1</sup> of metal at 318 K, respectively. The removal percentage was found to be higher for Pb (II) when compared with Cu (II).</p>}, number={49}, journal={Mongolian Journal of Chemistry}, author={Byamba-Ochir, Narandalai and Muratbyek, Nazgul and Tumen-Ulzii, Narangarav and Alyeksandr, Ariunaa and Oyunchimeg, Nasantogtokh}, year={2022}, month={May}, pages={1–8} }
