Zusammenfassung:The invention belongs to the technical field of separation functional materials, and discloses a method for preparing a zirconium oxide composite adsorbent based on a liquid drop confinement space and defluorination application of the zirconium oxide composite adsorbent. Lipase is fixed on the surface of styrene particles as a 'bridge', and abundant and uniformly distributed groups on the surface of the lipase provide an excellent platform for uniform growth of nano-particles, so that enzyme-linked particles are prepared. A continuous phase film of HIPEs is used as a framework to construct a flexible confinement space, and in the space, zirconium oxide nanoparticles are controllably and uniformly loaded on the surfaces of enzyme-linked particles, so that the zirconium oxide composite adsorbent is obtained. The problems that in the prior art, a nano zirconium oxide adsorbent is not easy to collect, large column pressure and low separation efficiency are easily caused during dynamic separation are solved, meanw
