Embodiment 1

[0047] The application of a ternary metal-organic framework bactericidal material based on heterogeneous Fenton-like reaction in inhibiting food-borne pathogenic bacteria, the steps are as follows:

[0048] (1) Dissolve nickel acetate, cobalt acetate and ferrous acetate in 10 mL of N,N-dimethylformamide in a ratio of 6:3:1 (total substance amount is 1 mmol) to obtain liquid A, Dissolve 1mmol of 2-aminoterephthalic acid into 5mL N,N-dimethylformamide to obtain liquid B, then pour liquid A into liquid B under magnetic stirring (300rpm), and mix and react at room temperature for 1.5h ; After the reaction, the product was obtained by centrifugation, washed twice with N,N-dimethylformamide and ethanol, and then vacuum-dried at 60°C for 12 hours to obtain the bactericidal material NiCoFe-MOF, which was stored in a sealed container at room temperature;

[0049] (2) Prepare Fe-MOF, Co-MOF and Ni-MOF respectively according to the same method of step (1), wherein ferrous acetate, cobalt...

Abstract

The invention discloses a ternary metal organic framework bactericidal material, a preparation method and an application thereof. The method is as follows: using a solvent as a reaction medium, uniformly mixing nickel acetate, cobalt acetate, ferrous acetate and 2-aminoterephthalic acid, and reacting at room temperature for 1 to 3 hours to obtain a nano-flower-shaped ternary metal-organic framework bactericidal material . The ternary metal-organic framework bactericidal material of the present invention is in the shape of a nano-flower, and has a good bactericidal effect, and nickel, cobalt, and iron are specifically sterilized directly and are effective against H 2 o 2 The dual function of decomposition, catalysis and sterilization. Compared with the prior art, the present invention combines metal-organic frameworks and heterogeneous Fenton-like reactions to achieve the purpose of efficient and synergistic sterilization, effectively reducing the amount of bactericidal materials and H 2 o 2 Dosage is used, thereby reducing toxic and side effects, and increasing the bactericidal material and H 2 o 2 utilization rate.

Description

technical field [0001] The invention belongs to the field of food sterilization, and in particular relates to a ternary metal-organic framework bactericidal material based on heterogeneous Fenton-like reaction, and a preparation method and application thereof. Background technique [0002] Foodborne diseases refer to a class of diseases that are caused by various pathogenic factors and have infectious or poisonous properties. Food-borne pathogens are an important source of food-borne disease outbreaks and an important risk hazard for food safety issues. They usually exist in foods rich in nutrients (protein, starch, oil, etc.) and high in water content, such as dairy products , meat, ice cream, leftovers, etc. [0003] Currently common sterilization methods include chemical disinfectants (such as ClO 2 , ethylene oxide), ultraviolet sterilization technology and antibiotics, etc. However, these sterilization methods usually have disadvantages such as harmful by-products, lo...
