The invention provides a photocatalytic adsorbent, a preparation method thereof and application thereof in sewage treatment, wherein the adsorbent is loaded with Fe 3 O 4 Graphene oxide-halloysite nanotube aerogel of-CdS-Ag, the specific surface area of which is 3200-3510m 2 Per g, density of 0.15-0.17mg/cm 3 . The photocatalytic adsorbent prepared by the invention has the advantages of simple preparation process, low cost and strong operability, and the obtained adsorbent can quickly adsorb and remove heavy metal ions in sewage, such as arsenic ions, cobalt ions, miscellaneous algae and bacteria, organic pollutants and CO 2 The magnetic field-based photocatalytic adsorbent has high-efficiency adsorption effect, magnetism and sterilization, can be used for removing cobalt ions from sewage, and can be used for efficiently removing the photocatalytic adsorbent after sewage purification, so that aftertreatment is facilitated, and the magnetic field-based photocatalytic adsorbent has wide application prospect. |
