Embodiment 1

[0025] Embodiment 1: take 100g attapulgite clay and be mixed with the ore slurry that quality is 20%, then add the composite acid modifier of attapulgite clay quality 20% (wherein, the proportioning of acid modifier is that phosphoric acid accounts for 30% , formic acid accounted for 10%, citric acid accounted for 30%, fumaric acid accounted for 30%), stirred at room temperature for 4 hours, passed through a 200-mesh sieve to remove quartz impurities, then added C12mimBr with 15% of the mass of attapulgite clay, and gradually heated to 40 ° C for 4 hours Afterwards, centrifuge, wash with water and ethanol in sequence, dry at 80°C for 4 hours, and then pulverize to obtain attapulgite zearalenone adsorbent with antibacterial function.

Embodiment 2

[0026] Embodiment 2: take 100g attapulgite clay and be mixed with the ore slurry that quality is 20%, then add attapulgite clay quality 10% composite acid modifier (wherein, the proportioning of acid modifier is that phosphoric acid accounts for 30%, Lactic acid accounted for 30%, citric acid accounted for 20%, fumaric acid accounted for 20%), stirred at room temperature for 4 hours, passed through a 200-mesh sieve to remove quartz impurities, then added C14mimBr with 10% of the mass of attapulgite clay, gradually heated to 60°C for 6 hours, and then centrifuged , washed with water and ethanol in turn, dried at 105°C for 4 hours, and pulverized to obtain attapulgite zearalenone adsorbent with antibacterial function.

Embodiment 3

[0027] Embodiment 3: take 100g attapulgite clay and be mixed with the ore slurry that quality is 20%, then add attapulgite clay quality 5% composite acid modifier (wherein, the proportioning of acid modifier is that sulfuric acid accounts for 30%, Formic acid accounted for 20%, malic acid accounted for 30%, succinic acid accounted for 20%), stirred at room temperature for 4 hours, passed through a 200-mesh sieve to remove quartz impurities, and then added attapulgite clay with 5% mass of [C16mim][PF 6 - ], gradually heated to 80°C for 8 hours, centrifuged, washed with water and ethanol in turn, dried at 105°C for 4 hours, and then pulverized to obtain attapulgite zearalenone adsorbent with antibacterial function.

Abstract

The invention discloses a preparation method of an antibacterial attapulgite zearalenone adsorbent. The preparation method comprises the following steps: performing acidification treatment on attapulgite with a compound acidifier, screening to remove quartz and carbonate impurities, adding an ionic liquid surfactant and performing reaction for 4-12 hour at the temperature of 40-90 DEG C; and separating, washing, drying and crushing the product to obtain the antibacterial attapulgite zearalenone adsorbent. The prepared attapulgite zearalenone adsorbent is not only capable of adsorbing and removing mycotoxin out of feed and also has an antibacterial function and the usage of antibiotics in the feed can be reduced.

Description

technical field [0001] The invention relates to a preparation method of an attapulgite zearalenone adsorbent with antibacterial function, and belongs to the field of deep processing of non-metallic ores. Background technique [0002] Mycotoxin contamination of feed and feed ingredients due to mildew has become a global problem. Zearalenone (Zearalenone, ZEN, chemical name 6-(10-hydroxy-6-oxo-undecenyl) β-rapenolide) is produced by Fusarium graminearum Steroids, mycotoxins with estrogen activity, have strong reproductive toxicity and teratogenic effects, can cause hyperestrogenism in animals, cause infertility or abortion in animals, and can also reduce the immunity of animals, thereby inducing other diseases . In addition, ZEN is difficult to metabolize in animals, and accumulates and remains in livestock and poultry products. After these toxins enter the human body, they can induce DNA shrinkage, cause tumors, cause chromosome abnormalities, and cause great harm to the hu...
