The application relates to a COF adsorbent for efficiently and selectively recovering Pb (II) and application thereof, and belongs to the field of high-efficiency adsorbents for adsorbing heavy metals and high-sensitivity electrochemical sensors. A Schiff base reaction occurs between benzene [1,2-b:3,4-b':5,6-b'] trithiophene-2,5,8-trialdehyde (BTT) and 3,3'-dihydroxybenzidine (DHBD) to obtain BTT-DHBD-COF, which has excellent adsorption performance on Pd (II), and the adsorption capacity can reach 570.7 mg / g after 10 min of adsorption; the detection limit of BTT-DHBD-COF / GCE on Pb (II) is 3*10 ‑12 mol L ‑1 .

Embodiments of the present application disclose information screening interaction method and device and electronic equipment. The method comprises: displaying a target page, the target page comprising a first area and a second area, the first area being configured to display information of a plurality of data objects, the second area being configured to provide a sliding bar element and a sliding control element movable along the sliding bar element; the sliding bar element comprising a plurality of sliding areas, the plurality of sliding areas corresponding to a plurality of selectable screening condition values when screening the plurality of data objects in a target dimension; in response to an operation of dragging the sliding control element, determining a selected target screening condition value according to a sliding area where the sliding control element is dragged to; and updating the first area after screening the plurality of data objects according to the target screening condition value. Through the embodiments of the present application, the interaction efficiency of the information screening process can be improved.
