Problems solved by technology

Among them, although high-temperature incineration can effectively degrade the active ingredients in medicines, it consumes a lot of energy and is likely to cause secondary pollution to the environment; while landfilling is difficult to biodegrade the relatively stable active ingredients in expired medicines, which is not conducive to ecology environmental protection
As for the expired medicines produced by household storage, due to the relatively scattered distribution, low awareness of social environmental protection and high recycling costs, these expired medicines are often directly discarded as regular garbage, and the remaining active ingredients are more likely to enter the ecological environment.
In short, there is currently no effective and systematic recovery and application system for expired tetracycline antibiotics, which not only seriously affects the ecological environment, but also wastes resources. It is urgent to develop new application methods in the recovery of tetracycline drugs

Embodiment 1

[0026] Embodiment 1: a kind of application method of expired tetracycline antibiotic medicine, concrete steps are as follows:

[0027] (1) Grind expired tetracycline tablets into powder and test its microscopic appearance, as shown in figure 2 shown by figure 2 It can be seen that the tetracycline drug powder presents an irregular particle shape, and the particle size is not greater than 10 μm; then the expired tetracycline powder, conductive graphite and polyvinyl alcohol are mixed uniformly to obtain an electrode material mixture, and the electrode material mixture is added to N-methylpyrrolidone In the solvent, stir evenly to obtain the electrode slurry; in which, in terms of mass percentage, the expired tetracycline powder in the electrode material mixture accounts for 60%, the conductive agent (conductive graphite) accounts for 30%, and the binder (polyvinyl alcohol) accounts for 10%;

[0028] (2) The electrode slurry obtained in step (1) was evenly coated on the surfa...

Embodiment 2

[0030] Embodiment 2: a kind of application method of expired tetracycline antibiotic medicine, concrete steps are as follows:

[0031] (1) After the particles in the expired tetracycline capsules were further ground, the microstructure was detected by Fourier transform infrared spectroscopy, such as image 3 shown by image 3 It can be seen that at 3421 cm -1 、1257 cm -1 、740cm -1 The left and right respectively correspond to the stretching vibration, in-plane bending vibration and out-of-plane bending vibration of the N-H bond; at 3676 cm -1 、1398cm -1 , and 670 cm -1 corresponding to the stretching vibration, in-plane bending vibration and out-of-plane bending vibration of the O-H bond; at 2922 cm -1 、1327 cm -1 and 860 cm -1 The nearby peak corresponds to -CH 3 The stretching vibration, in-plane bending and out-of-plane bending vibration; the stretching vibration of C=O is the same as that at 1640cm -1 and 1609 cm -1 The left and right peaks correspond to 1508 cm...

Embodiment 3

[0034] Embodiment 3: a kind of application method of expired tetracycline antibiotic medicine, concrete steps are as follows:

[0035] (1) The particles in the expired tetracycline capsules are further pulverized and then mixed with acetylene black and sodium carboxymethylcellulose to obtain an electrode material mixture. Add the electrode material mixture to N-methylpyrrolidone solvent and stir evenly to obtain an electrode slurry Among them, in terms of mass percentage, the expired tetracycline drug powder in the electrode material mixture accounts for 70%, the conductive agent (acetylene black) accounts for 20%, and the binder (sodium carboxymethyl cellulose) accounts for 10%;

[0036] (2) The electrode slurry obtained in step (1) was evenly coated on the surface of the nickel foil current collector, and vacuum-dried at 60°C for 12 h to obtain an electrode sheet;

[0037] (3) Assemble a button-type simulated sodium ion battery in a glove box filled with high-purity argon: t...

Abstract

The invention discloses an application method of expired tetracycline antibiotics and belongs to the technical field of new energy materials. In the present invention, the expired tetracycline antibiotics are ground into powder, mixed with a conductive agent and a binder to obtain an electrode material mixture, and the electrode material mixture is added to N-methylpyrrolidone solvent, and stirred evenly to obtain an electrode slurry; the electrode slurry Evenly coated on the surface of the current collector, vacuum-dried to obtain the electrode sheet; the electrode sheet is used as the working electrode, lithium foil or sodium foil is used as the counter electrode and reference electrode, and porous polypropylene film, polyethylene film, glass fiber or non-woven fabric is The diaphragm is assembled into a lithium-ion rechargeable battery or a sodium-ion rechargeable battery under anhydrous and oxygen-free conditions. The invention is environmentally friendly, has strong practicability, and is low in cost. The expired tetracycline antibiotic medicine is used in the field of new energy materials for the first time, and a new way and a new scheme are provided for recycling and using the expired antibiotic medicine.

Description

technical field [0001] The invention relates to an application method of expired tetracycline antibiotics, belonging to the technical field of new energy materials. Background technique [0002] With the rapid development of the socio-economic level and the rapid improvement of people's health awareness, the production of drugs has been increasing year by year. Once the supply exceeds the demand, it is easy to produce a large number of expired drugs. Improper handling of expired drugs will cause the residual active ingredients to enter the environment and cause negative impacts on the ecosystem, especially the environmental pollution and ecotoxicity of antibiotics has attracted widespread attention. Among them, tetracycline antibiotics have the advantages of broad-spectrum antibacterial, high quality and low price, and have the effect of inhibiting bacterial protein synthesis. They are often used to treat a variety of bacterial infections and are currently a widely used cla...
