N2 - In this work, a novel flowerlike BSA/Zn3(PO4)2/Fe3O4 magnetic hybrid particle is successfully synthesized through a simple and rapid one-step strategy. The kernel is to introduce Fe3O4 nanoparticles in the process of the precipitation and coordination reaction of Zn2+ ions with phosphate radical and BSA. The average diameter of the magnetic hybrid particle is 2.3 μm. The specific surface area is 51.61 m2/g, the average pore size is 15.30 nm. The saturation magnetization is 9.5 emu·g-1. The effects of the dosage of BSA and Fe3O4 nanoparticles on the properties of the magnetic hybrid particles are systematically investigated and optimized. The as-obtained BSA/Zn3(PO4)2/Fe3O4 magnetic hybrid particle is used for the removal of Cu2+ ions. The results reveal that the magnetic hybrid particles present excellent adsorption performance on Cu2+ ions with low concentration. The adsorption isotherms are fitted with the Langmuir equation. The maximum adsorption capacity is 12.56 mg·g-1 at 306 K estimated by the Langmuir model. It can maintain more than 90% of its initial capacity after 10 times of successive reuse. Meanwhile, the magnetic property brings great convenience to the reuse of the absorbent.
