Abstract

The invention relates to a preparation method of a rare earth loaded antibacterial agent. The preparation method of the rare earth loaded antibacterial agent comprises the following steps: dispersing a certain amount of Q high-flow-speed agarose microspheres into ethanol, adding bi(pentamethyl cobalt cyclopentene) and 1-allyl-3-methylimidazolium chloride, and performing polymerization to obtain rare earth-containing Q high-flow-speed agarose microsphere micro-suspension products subjected to surface polymerization.

Description

technical field [0001] The invention relates to a preparation method of an antibacterial agent, in particular to a preparation method of a rare earth loaded antibacterial agent. Background technique [0002] Rare earth elements and their compounds have good anti-inflammatory, bactericidal, anti-cancer, anti-coagulation, and analgesic effects. Heterocyclic compounds are a class of compounds with a wide range of biological activities. Many heterocyclic compounds have biological activities such as sterilization, anti-inflammation, and anti-virus, so they have attracted much attention. After the heterocyclic compound forms a complex with metal ions, the antibacterial effect of the metal complex will be enhanced due to the synergistic effect. Relevant studies have shown that compared with many organic synthetic drugs, rare earth complexes have lower toxicity, and at the same time, no accumulation in the body has been found through oral or external use of rare earth complexes, so...
