Abstract:
1. A preparation method of filter element for swift and highly efficient adsorption of Cs, the method comprising: 1) mixing a substrate material, a coupling agent with 1-3 wt % and ammonium phosphomolybdate with 1-10 wt %, based on a weight of the substrate material and heating the mixture to 160˜220° C., the substrate material being combined with ammonium phosphomolybdate; 2) spinning the material prepared in 1) through 5 μm micropore to form an adsorbent filter element with a thickness of 5˜50 mm in rotational cylinder framework material; 3) evenly coating ammonium phosphomolybdate on a surface of the adsorbent filter element obtained in 2) so that ammonium phosphomolybdate is combined with the ammonium phosphomolybdate within the substrate material; 4) heating the filter element obtained in 3) to 80˜120° C. for 3-12 h, thereby obtaining the filter element for swift and highly efficient adsorption of Cs.
