The magnetic magnesium silicate composite (Fe 3 O 4 @MgSi) with efficient removal of Cu(II) and malachite green (MG) from aqueous solution were synthesized by hydrothermal approach. 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 −1 when the Cu(II) concentration of 800 mg•L −1 . These results indicated that Fe 3 O 4 @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.
