  • Magnetic adsorbent for removing arsenic and antimony by means of adsorption-superconducting magnetic separation and preparation method therefor
    Patent number: 11135562
    Abstract: A magnetic adsorbent, preparation method therefor and application thereof. The magnetic adsorbent is made by loading a weakly material with high adsorption capacity, an iron-based gel, onto a strongly magnetic ferrite material with low adsorption capacity by means of in-situ reaction. The magnetic adsorbent is used for removing heavy metal pollutants and phosphate pollutants from water.
    Type: Grant
    Filed: December 22, 2019
    Date of Patent: October 5, 2021
    Assignee: Research Center for Eco-Environmental Sciences
    Inventors: Ruiping Liu, Zenglu Qi, Lijun Zhu, Huijuan Liu, Huachun Lan, Jiuhui Qu
