Embodiment 1

[0022] Step 1, preparation of modified attapulgite (ATP): get 10~20g attapulgite and add to 100~200mL hydrochloric acid (1molL -1 ) solution, sealed and magnetically stirred for 2-3h to disperse evenly, ultrasonicated for 0.5-1h, centrifuged to obtain a solid sample, placed in an oven at a certain temperature, and vacuum-dried for 8h to obtain modified ATP.

[0023] Step 2. Take 0.005g of ATP and disperse it into 20mL of ethanol, then add 5g of urea to dissolve and seal it, magnetic stirring time is 3h, ultrasonic time is 0.5h, and the product is vacuum-dried for 8h. Then the mixture was placed in a crucible and sealed with aluminum foil, and calcined at a high temperature in a muffle furnace at 500°C, and the heating rate was 1.0°C / min. After the temperature of the muffle furnace was cooled to room temperature, the crucible was taken out and the solid sample in the crucible was ground into powder, and then the sample was dried in an oven to obtain yellow ATP-modified g-C 3 N...

Embodiment 2

[0026] Step 1, preparation of modified attapulgite (ATP): get 20g of attapulgite and add to 100mL hydrochloric acid (1mol L -1 ) solution, sealed with magnetic stirring for 3 hours until uniformly dispersed, ultrasonicated for 1 hour, centrifuged to obtain a solid sample, placed in an oven at a certain temperature, and vacuum-dried for 8 hours to obtain modified ATP.

[0027] Step 2. Take 1.0 g of ATP and disperse it into 20 mL of ethanol, then add 5 g of urea to dissolve and seal it, magnetic stirring time is 5 h, ultrasonic time is 2 h, and the product is vacuum-dried for 8 h. The mixture was then placed in a crucible and sealed with aluminum foil, and calcined at a high temperature in a muffle furnace at 500°C with a heating rate of 10°C / min. After the temperature of the muffle furnace was cooled to room temperature, the crucible was taken out and the solid sample in the crucible was ground into powder, and then the sample was put into an oven to dry to obtain yellow ATP-mo...

Embodiment 3

[0030] Step 1, preparation of modified attapulgite (ATP): get 15g attapulgite and add to 150mL hydrochloric acid (1mol L -1 ) solution, sealed magnetic stirring for 1.5h until uniform dispersion, ultrasonication for 0.8h, placed in an oven at a certain temperature and vacuum-dried for 8h to obtain modified ATP.

[0031] Step 2. Take 0.01 g of ATP and disperse it in 20 mL of ethanol, then add 5 g of urea to dissolve and seal it, magnetic stirring time is 4 h, ultrasonic time is 1.5 h, and the product is vacuum-dried for 8 h. Then the mixture was placed in a crucible and sealed with aluminum foil, and calcined at a high temperature in a muffle furnace at 500°C, and the heating rate was 5°C / min. After the temperature of the muffle furnace was cooled to room temperature, the crucible was taken out and the solid sample in the crucible was ground into powder, and then the sample was dried in an oven to obtain yellow ATP-modified g-C 3 N 4 . marked as g-C 3 N 4 @ATP photocatalys...

Abstract

The invention provides a preparation method and application of a binary intercalation mesoporous g-C3N4@ATP composite photocatalyst. The preparation method comprises the following steps: 1, adding attapulgite into hydrochloric acid, sealing, performing magnetic stirring till uniformly dispersing, performing ultrasonic treatment, standing, performing centrifugal separation so as to obtain a solid sample, and performing vacuum drying so as to obtain modified attapulgite; and 2, dispersing the modified attapulgite into ethanol, further adding urea, sealing, performing magnetic stirring to dissolve solute, collecting a solid product, performing vacuum drying, further calcining the solid product in a muffle furnace, and after the temperature of the muffle furnace is reduced to the room temperature, taking out a crucible, grinding the solid sample in the crucible into powder, and drying the solid in an oven, thereby obtaining attapulgite modified g-C3N4, wherein the substance is yellow and is marked as a g-C3N4@ATP photocatalyst. The preparation method provided by the invention is unique, and the prepared g-C3N4@ATP composite photocatalyst is novel in structure and has relatively high photocatalytic activity and stability in tetracycline degrading.

Description

technical field [0001] The invention belongs to the technical field of environmental material preparation, in particular to a binary intercalation structure g-C based on mesoporous carbon nitride 3 N 4 The preparation method and application of @ATP composite photocatalyst. Background technique [0002] Antibiotics, formerly known as antibiotics, are a class of secondary metabolites produced by microorganisms (including bacteria, fungi, actinomycetes) or higher animals and plants during the growth process with anti-pathogen or other activities. Chemicals that function in other cell development. It can not only kill bacteria, but also have a good inhibitory and killing effect on mold, mycoplasma, chlamydia, spirochetes, rickettsia and other pathogenic microorganisms, which plays an extremely important role in human health and life safety. At present, whether it is cold patients, hospitalized patients or surgical operations, the use of antibiotics is extremely common. The c...
