Embodiment 1

[0042] This embodiment provides a kind of preparation method of the material that adsorbs aflatoxin and zearalenone;

[0043] Weigh 2g of sodium carbonate, dissolve it in 500mL of distilled water, i.e. 0.4% sodium carbonate solution, add 50g of natural montmorillonite, stir to a uniform suspension, place it in a water bath at 60°C, stir rapidly for 2h, after the sodiumization reaction is completed , adjust the pH value to 9.5 with 1mol / L sodium hydroxide solution.

[0044] Add 7.5g of cetyltrimethylammonium chloride, stir well, place in a water bath at 60°C, and stir rapidly for 3h. Then take it out, let it settle naturally for 2 hours, discard the supernatant, and dry and pulverize the obtained precipitate at 80°C, and pass through a 200-mesh sieve. Adsorption materials that can be used to adsorb aflatoxin and zearalenone are obtained.

Embodiment 2

Abstract

The invention discloses a method for preparing a method capable of adsorbing aflatoxin and zearalenone. The method comprises the following steps: (1) dispersing montmorillonite in a 0.4-0.8wt% sodium modification agent solution, uniformly stirring, stirring at the temperature of 60-90 DEG C for 1-3 hours, and regulating the pH value to 9.5-10.5 by using a sodium hydroxide solution after a sodium modification reaction is ended; (2) adding a quaternary ammonium salt surfactant and mixing at the temperature of 60-90 DEG C for 2-5 hours; and (3) standing and settling the obtained precipitate, drying and crushing, thus obtaining the finished product, wherein the following materials are used in parts by weight: 30-100 parts of montmorillonite, 200-700 parts of 0.4-0.8wt% sodium carbonate and 5-25 parts of quaternary ammonium salt surfactant. The method is simple in process, and the finished product prepared by the method is high in stability, high in adsorption speed and excellent in adsorption property and can simultaneously adsorb aflatoxin B1 and zearalenone.

Description

technical field [0001] The invention relates to an adsorption material, in particular to a material for adsorbing aflatoxin and zearalenone and a preparation method thereof. Background technique [0002] Mycotoxins are anti-nutritional factors that are ubiquitous in feed and feed ingredients, and are secondary metabolites of mold with strong toxins. According to the data of the Food and Agriculture Organization of the United Nations, about 25% of the feed and feed materials in the world are polluted by mycotoxins to varying degrees. [0003] Animals often suffer from acute and chronic toxicity after eating feed contaminated by mycotoxins, leading to the occurrence of tumors and cancers (mainly liver cancer and kidney cancer), estrogen disorder syndrome, and suppression of immune function, which not only cause losses to breeders, but also It will further affect human health due to the decline in the quality of animal products. According to the United States Department of Ag...
