The invention discloses a preparation method of a carbon nitride-based oxytetracycline residue scavenger, which comprises the following steps: first, mixing MoS 2 , g-C 3 N 4 and deionized water, and ultrasonically treating it; putting it into an autoclave , perform a hydrothermal reaction to obtain a MoS 2 /g-C 3 N 4 complex; disperse the MoS 2 /g-C 3 N 4 complex in a mixed solution of deionized water and methanol, stir, and then add the MoS 2 /g-C 3 N 4 complex to the solution. Add chloroauric acid solution, irradiate it with a xenon lamp, and blow with an air pump; wash and dry to obtain AuNPs/MoS 2 /g-C 3 N 4 three-phase composite material, which is an oxytetracycline residue scavenger. The use of nano-gold and MoS 2 dual-sensitized g-C 3 N 4 composite material can remove antibiotic residues, the preparation process requires low equipment, mild reaction conditions, and the synthesis process is simple and easy to implement. |
