Embodiment 1

[0036] The present invention is a kind of preparation method of the oxytetracycline residue scavenger based on carbon nitride, specifically implement according to the following steps:

[0037]Weigh MoS 2 0.004g; then take g-C 3 N 4 0.796g. Take 0.004g MoS 2 with 0.796g g-C 3 N 4 Place in the same beaker, add 60mL of deionized water, and sonicate for 1h. Then it was put into an autoclave and kept at 150° C. for 10 h. After the reaction is over, take out the autoclave and open it in the fume hood to get 0.5% MoS 2 / g -C 3 N 4 Composite photocatalytic materials. Prepare 10mL of 48.56mM chloroauric acid solution for later use (protect from light and store in dry conditions). Take 0.1895g of 0.5% MoS 2 / g -C 3 N 4 The complex was added to a mixed solution of 40 mL deionized water and 10 mL methanol, and stirred at room temperature for 1 h. Accurately measure two parts of 2.320mL chloroauric acid solution and add to 0.2g 0.5% MoS 2 / g -C 3 N 4 in the complex. Un...

Embodiment 2

[0045] A kind of preparation method of the oxytetracycline residue scavenger based on carbon nitride of the present invention, specifically implement according to the following steps:

[0046] Weigh MoS 2 0.008g; then take g-C 3 N 4 0.796g. Take 0.008g MoS 2 with 0.796g g-C 3 N 4 Put it in the same beaker, add 60ml of deionized water, and sonicate for 1h. Then it was put into an autoclave and kept at 160° C. for 10 h. After the reaction is over, take out the autoclave and open it in a fume hood to obtain 1% MoS 2 / g -C 3 N 4 Composite photocatalytic materials. Prepare 10mL of 48.56mM chloroauric acid solution for later use (protect from light and store in dry conditions). Take 0.1778g 1%MoS 2 / g -C 3 N 4 The complex was added to a mixed solution of 40 mL deionized water and 10 mL methanol, and stirred at room temperature for 1 h. Accurately measure two portions of 1.100 mL of chloroauric acid solution and add to 0.1778 g of 1% MoS 2 / g -C 3 N 4 in the compl...

Abstract

The invention discloses a preparation method of an oxytetracycline residue scavenger based on carbon nitride, which comprises the following steps: mixing MoS2, g-C3N4 and deionized water, and carrying out ultrasonic treatment; putting into a high-pressure kettle, and carrying out a hydrothermal reaction to obtain a MoS2 / g-C3N4 compound; dispersing the MoS2 / g-C3N4 compound into a mixed solution of deionized water and methanol, stirring, adding a chloroauric acid solution into the solution, irradiating the solution by using a xenon lamp, and blowing air by using an air pump; filtering, washing and drying to obtain an AuNPs / MoS2 / g-C3N4 three-phase composite material, namely the oxytetracycline residue scavenger. The g-C3N4 composite material doubly sensitized by nanogold and MoS2 can be used for removing antibiotic residues, the preparation process has low requirements on equipment, the reaction conditions are mild, and the synthesis process is simple and easy to implement.

Description

technical field [0001] The invention belongs to the technical field of material preparation, and in particular relates to a preparation method of a carbon nitride-based oxytetracycline residue scavenger. Background technique [0002] As one of the most serious environmental pollutants, antibiotic residues have become increasingly serious potential threats to human health and ecosystems, and have attracted widespread attention. Oxytetracycline is a broad-spectrum antibiotic widely used in aquaculture and livestock and poultry farming, and it is also one of the antibiotics with the largest output in the world. Due to its long half-life, oxytetracycline, which is discharged in large quantities in water bodies and soil environments, is not easy to be biodegraded, resulting in a large amount of residues in the environment. In addition, the residue of oxytetracycline can provide a good breeding and transmission environment for drug-resistant bacteria and drug-resistant genes, and...
