Problems solved by technology

However, this method needs to be prepared by a two-step hydrothermal method. First, the metal source solution is synthesized, and then hydrothermal vulcanization is carried out. The preparation process is cumbersome, and it is easy to release H 2 S gas, not friendly to the ecological environment
[0004] Chinese patent CN 106192009 A discloses a quaternary sulfide semiconductor photocatalytic material for antibacterial and anticorrosion of concrete surface and its preparation method, and found that it has good effect on T-sulfur oxidizing bacteria, Thiobacillus X and Silicophage Inhibition effect, but this method needs to be reacted under high temperature conditions for 5 days, and the required time is too long

Embodiment 1

[0026] Solvothermal synthesis is used to prepare ternary sulfides.

[0027] (1) Weigh AgNO 3 0.85 g (or Cu(NO 3 ) 2 ·3H 2 O 2.42 g) and Bi(NO 3 ) 3 ·3H 2 A mixed solution of 2.42 g of O dissolved in 30 mL of ethylene glycol;

[0028] (2) Weigh 1.52 g of thiourea and dissolve it in 20 mL of ethylene glycol, mix it with the mixed solution obtained in step (1) and stir for 30 minutes to obtain the precursor solution;

[0029] (3) Weigh 1.0 g of soy flour, panax notoginseng powder, chlorophyll, rubber latex, and perylenequinone, and dissolve it in 10 mL of ethylene glycol to obtain a solution;

[0030] (4) Drop the dissolved solution obtained in step (3) into the precursor solution, and stir for 3 h at a temperature of 25°C;

[0031] (5) Put the product obtained in step (4) into a stainless steel reactor and react at 200 ℃ for 24 h;

[0032] (6) The product obtained in step (5) is taken out and cooled, filtered first, washed with absolute ethanol and distilled water, and dried at 90 ℃ to ob...

Embodiment 2

[0035] Example 2 (application):

[0036] Antibacterial activity test

[0037] The medium used in this experiment is beef extract agar medium. Bacillus subtilis is evenly dispersed in sterile physiological saline 0.9% (W / V), the filter paper is punched into 6 mm filter paper sheets, autoclaved and then dried and immersed in sterile liquids of different concentrations. The filter paper of the control group was immersed in sterile water. Spread the bacterial suspension on the surface of the culture medium and incubate it in a constant temperature incubator at 37°C for 24 hours. Use sterile tweezers to take the antibacterial tablet and place it on the surface of the plate. Cover the flat dish and place it in the constant temperature incubator at 37°C. Incubate in medium for 24 h, and then measure the size of the inhibition zone in the three types of petri dishes, select the material with the larger inhibition zone, and conduct the TEM measurement experiment.

Abstract

The invention relates to an inorganic antibacterial material synthesized by taking natural plants as raw materials and a method. Soybean powder, dencichine, a rubber emulsion, chlorophyll, perylenequinone and ethylene glycol are used as raw materials, and inorganic antibacterial materials with different morphologies are prepared by adopting a solvothermal synthesis method. Compared with other technologies, the method has the advantages that eco-friendly and non-toxic biological materials with different morphologies, such as soybean meal, dencichine, rubber latex, chlorophyll and perylenequinone, are used as raw materials, the morphology of the inorganic material is controlled within a certain range, and the characteristics of the inorganic material are used for inhibiting bacillus subtilis.

Description

Technical field [0001] The present invention belongs to the field of inorganic material antibacterial technology, and specifically relates to a method and application for synthesizing inorganic materials using natural plants as raw materials for antibacterial. Background technique [0002] Inorganic antibacterial material is a kind of natural or synthetic inorganic material with bactericidal activity that contains unbound particles or as aggregates or agglomerates. Due to its low toxicity, high stability, good durability, it is not easy to cause The advantages of bacterial resistance have become a focus of research in antibacterial materials. Among them, silver and copper metal antibacterial materials have become the main antibacterial materials due to their high efficiency, spectrum, low toxicity, and no environmental pollution. Sulfine has a suitable band gap and a good band edge position and is considered a promising semiconductor. Therefore, using the antibacterial activity...
