Problems solved by technology

Although heavy metal ions can kill bacteria, they are easy to deposit in the body after desorption from the carrier and are not easy to be discharged, so their application is limited

Embodiment

[0013] (1) Pulverize the zeolite into 200 meshes, and destroy the structure of the zeolite under the treatment of hydrochloric acid with a mass percentage of 15%, and become an amorphous amorphous state, which is used as a precursor for preparing a zeolite molecular sieve. In the molar mass ratio of acidified hematite:NaOH:NaAlO 2 :H 2 Under the condition of O=1:2:1:48, the NaOH with a mass concentration of 96% and the NaAlO with a mass concentration of 41% were first 2 Prepared into a solution and added to the reactor in turn to synthesize zeolite molecular sieves (Na 2 O·Al 2 o 3 2SiO2 2 4.5H 2 O), the crystallization time was 6 hours, and the crystallization temperature was 90°C. The prepared zeolite molecular sieve has a whiteness of 97 percent, a crystallinity of 98 percent, and a volume average particle diameter of 3-5 μm, reaching the industry standard Q / Chalco A021-2004 for molecular sieves used for adsorption grafting agents.

Abstract

The invention discloses a method for preparing a feed antibacterial agent by absorbing and grafting potassium diformate on an epidesmine molecular screen. Regarding the defects that heavy metals in a silver zeolite antibacterial agent easily deposit in a body and cannot be applied to a feed, and the acidating agent potassium diformate cannot plays roles in intestinal tracts, the method takes the modified epidesmine as a carrier to adsorb the acidating agent potassium diformate so as to prepare the feed epidesmine antibacterial agent. Acidity detection and in vitro antibacterial tests indicatethat: the feed epidesmine antibacterial agent has sustained release performance, has an excellent bacteriostasis effect to escherichia coli, and can prevent and treat diarrhea caused by the escherichia coli.

Description

technical field [0001] The invention relates to a method for preparing a fodder stilbite antibacterial agent by using molecular sieve prepared from hematite as a carrier, and absorbing grafted acidifying agent potassium diformate. Background technique [0002] Escherichia coli causes diarrhea in young animals, resulting in a low survival rate (32%). The current solution is to add antibiotics to the feed. With the increase of antibiotic resistance of pathogenic bacteria, the extensive use of antibiotics will produce resistance and residues in the environment, endangering human and animal health. Therefore, finding ways to reduce the amount of antibiotics or alternatives to antibiotics has become a research focus in various countries. In order to achieve the purpose of antibacterial, domestic and foreign efforts are devoted to loading antibacterial substances on various adsorption materials, such as utilizing the cation exchange properties of silicate minerals, adding Ag + 、C...
