The synthetic flower-like particle size was about 2–3 μm. In the process of exploring the adsorption conditions, the isotherms were found to be well-fitted by Langmuir, Freundlich, and isotherm kinetics in accord with the pseudo-second-order model. In addition, the maximum adsorption capacity was 2198 mg·g<sup>–1</sup> when the Cu­(II) concentration of 800 mg·L<sup>–1</sup>. These results indicated that Fe<sub>3</sub>O<sub>4</sub>@MgSi can be used as a superadsorbent and recyclable adsorbent to effectively and rapidly remove Cu­(II) and MG pollutants from industrial wastewater or drinking water.
