  • 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

  • Hollow iron-manganese composite material prepared by etching template process and application thereof
    Patent number: 10493425
    Abstract: A method for preparing a hollow hydroxyl iron-manganese composite by employing a cubic structure template comprises: (1) preparation of a template: adding a certain mass of potassium permanganate to diluted hydrochloric acid, and dissolving and mixing evenly the same by magnetic stirring at room temperature; then adding polyvinylpyrrolidone thereto, and continuing to dissolve the same thoroughly by magnetic stirring; and finally adding a certain mass of potassium ferrocyanide and de-solubilizing the same for 10-60 minutes at room temperature, then transferring the above mixed solution into a sample bottle, and performing an isothermal reaction at 50-90° C.
