Embodiment 1

[0022] The preparation of the adsorption material of embodiment 1 zearalenone (1)

[0023] step 1

[0024] Take nonionic surfactant Pluronic P123 (EO 20 PO 70 EO 20 ) 4.0g, dissolved in a mixed solution of 120mL deionized water and 20mL concentrated hydrochloric acid (37%), and added 3.0g KCl, stirred until clear. Then, 8.5 g of tetraethyl orthosilicate was added, and the mixed solution was vigorously stirred on a magnetic stirrer for 15 minutes, then transferred to a constant temperature water bath at 35° C., and left to stand for crystallization for 20 hours. The obtained white gel was transferred to a Teflon-lined hydrothermal kettle, and crystallized at 100° C. for 24 hours to obtain a white liquid-solid mixture.

[0025] step 2

[0026] The white liquid-solid mixture obtained in Step 1 was filtered, the filtered solid was washed with water until the pH was neutral, filtered with suction, and dried at 75° C. to obtain 10.5 g of an adsorption material that could be use...

Embodiment 2

[0028] Example 2 Preparation of Adsorption Material for Zearalenone (2)

[0029] Step 1: Same as Example 1.

[0030] Step 2: Filter the white liquid-solid mixture obtained in step 1, wash the filtered solid with water to pH 4.50, then transfer to 12ml of a mixed solution containing 0.03% sodium alginate and 0.01% chitosan, stir for 20min, and suction filter , collected the solid, and dried at 75° C. to obtain 10.7 g of zearalenone adsorption material.

[0031] The obtained adsorption material was used for the adsorption performance test of zearalenone, and the result was that the adsorption rate of zearalenone was 91.25%.

Embodiment 3

[0032] Example 3 Preparation of Adsorption Material for Zearalenone (3)

[0033] Step 1: Same as Example 1.

[0034] Step 2: Filter the obtained white liquid-solid mixture, wash the obtained filtrate with water to pH 5.50, add the solid to 12ml of the mixed solution of sodium alginate and chitosan with concentrations of 0.02% and 0.03% respectively, and stir for 20min , filtered with suction, collected the solid, and dried at 75° C. to obtain 10.4 g of zearalenone adsorption material.

[0035] The obtained adsorption material was used for the adsorption performance test of zearalenone, and the result was that the adsorption rate of zearalenone was 91.67%.

Abstract

The invention provides a material for adsorbing zearalenone. The material is prepared by using Pluronic P123, hydrochloric acid, KC1 and ethyl orthosilicate. An experiment proves that an adsorption rate of the adsorption material on zearalenone poisons is as high as 89.61%-92.73%, adsorption is rapid, stability is good, the adsorption material is simple and convenient in preparation method, and raw materials are easy to obtain.

Description

Technical field: [0001] The invention relates to a feed additive, in particular to a material capable of absorbing zearalenone and a preparation method thereof. Background technique: [0002] According to the data of the Food and Agriculture Organization of the United Nations, about 25% of the world's grains are polluted by mycotoxins to varying degrees every year, causing huge economic losses. Zearalenone (ZEN) is associated with an increasing number of livestock health problems, especially in pig farming. [0003] In the prior art, the function of aluminosilicate and clay substances for the adsorption of mycotoxins has been studied, such as montmorillonite (bentonite) and zeolite. However, natural montmorillonite can only be modified after complicated treatment, the process is complicated, and the cost is high. At the same time, the limited capacity of the inserted long-chain compound limits the adsorption capacity of zearalenone. [0004] Therefore, in practice, there i...
