| Summary: | The ternary composite MgO@ZnO@BC was synthesized and characterized for the adsorption of Cu<sup>2+</sup>, Pb<sup>2+</sup> heavy metal ions from wastewater. The results show that the addition of the MgO@ZnO@BC composite results in higher adsorption properties for Cu<sup>2+</sup> and Pb<sup>2+</sup>, with a molar ratio of 5% 0.1 g, and maximum adsorption capacity (50.63 mg/g for Cu<sup>2+</sup> and 61.46 mg/g for Pb<sup>2+</sup>). The Langmuir adsorption isotherm of the adsorption complex and the kinetics of adsorption are secondary kinetics. The adsorption of Cu<sup>2+</sup> and Pb<sup>2+</sup> was mainly chemisorption, accompanied by physical adsorption. This adsorption method fully conforms to the concepts of clean production and efficient waste utilization, providing a reference for the removal of heavy metal ions from wastewater and waste recycling using ternary composite materials.
