The invention relates to a TiO 2 /Er 3+ : YAlO 3 /NiFe 2 O 4 photocatalyst-enhanced method for degrading antibiotics by hydraulic cavitation. Firstly, nickel ferrite (NiFe 2 O 4 ) monomer with rod-like structure was prepared by hydrothermal method, secondly, Er 3+ : YAlO 3 monomer was synthesized by sol-gel and calcination method, and then Er 3+ : YAlO 3 monomer was synthesized by ultrasonic dispersion method. 3+ : YAlO 3 ‑NiFe 2 O 4 , and finally a new high-efficiency composite Z-type TiO 2 /Er 3+ : YAlO 3 /NiFe 2 O 4 photocatalyst was synthesized by sol-gel method. The TiO 2 /Er 3+ :YAlO 3 /NiFe 2 O 4 synthesized by the invention has magnetic properties, is easy to recycle, and can be better applied to degrade antibiotics in wastewater. |
