preparation example 1
[0032] Weigh a certain amount of montmorillonite, put it in deionized water, stir, and prepare a suspension with a mass fraction of 8%, and heat it to 60°C, and stir for 10 minutes; another certain amount of octadecyl trimethyl bromide Ammonium chloride, dissolved in deionized water, is prepared into a quaternary ammonium salt solution with a concentration of 10%; according to the volume ratio of the quaternary ammonium salt solution and the suspension of montmorillonite is 1:5, the quaternary ammonium salt solution is added to the montmorillonite In the desoiled suspension, continue stirring at 60°C for 5 hours; filter, and wash the precipitate with hot ethanol aqueous solution until there is no Br in the washing liquid - (with 0.1mol / L AgNO 3 inspection), and the sediment was dried at 65°C to obtain salt-modified montmorillonite.
Embodiment 1
[0035] A mycotoxin adsorbent for feed, made of the following raw materials, 150g Saccharomyces cerevisiae cell wall, 500g modified montmorillonite, 100g benzoic acid, 150g sodium benzoate and 100g ε-polylysine, wherein ε-polylysine The molecular weight is 3800.
[0036] The specific preparation method of the mycotoxin adsorbent for feed is as follows. Accurately weigh the cell wall of Saccharomyces cerevisiae, modified montmorillonite, benzoic acid, sodium benzoate and ε-polylysine, and mix well to obtain the mycotoxin adsorbent.
Embodiment 2- Embodiment 12
[0038] The mycotoxin adsorbents for feed in Example 2-Example 12 were all prepared by the method in Example 1, the only difference being that the dosage of each raw material component was different, see Table 2 for details:
[0039] The dosage of each raw material component in the embodiment 2-embodiment 12 of table 2
