Problems solved by technology

[0005] Naturally produced Yimon mixed clay has a hydrophilic negative surface charge, and has strong adsorption properties for mycotoxins with polar groups, such as aflatoxin, but it has a strong adsorption performance for mycotoxins with weaker polarity (such as corn erythralenone, etc.) with limited adsorption capacity

Embodiment 1

[0016] Example 1: Weigh dodecyltrimethylammonium bromide which is 5 times the cation exchange capacity of Yimon mixed clay, dissolve it in an appropriate amount of water, then add Yimon mixed clay to prepare a slurry with a mass concentration of 5%, and then react at 60°C 12h, the product was filtered and washed with AgNO 3 After checking for the absence of Br-, press filter, dry and pulverize to obtain the modified Imon mixed clay mycotoxin adsorbent. The in vitro removal efficiencies of the adsorbent for aflatoxin and zearalenone were 100 and 82%, respectively.

Embodiment 2

[0017] Example 2: Weigh tetradecyltrimethylammonium bromide which is 2 times the cation exchange capacity of Yimon mixed clay, dissolve it in an appropriate amount of water, then add Yimon mixed clay to prepare a slurry with a mass concentration of 5%, and then react at 75°C 6h, the product was filtered and washed with AgNO 3 After checking for the absence of Br-, press filter, dry and pulverize to obtain the modified Imon mixed clay mycotoxin adsorbent. The in vitro removal efficiencies of the adsorbent for aflatoxin and zearalenone were 100 and 78%, respectively.

Embodiment 3

[0018] Example 3: Weigh cetyltrimethylammonium bromide with 1.5 times the cation exchange capacity of Yimeng mixed clay, dissolve it in an appropriate amount of water, then add Yimend mixed clay to prepare a slurry with a mass concentration of 5%, and then react at 80°C 4h, filter the product, wash with water, and use AgNO 3 After checking for the absence of Br-, press filter, dry and pulverize to obtain the modified Imon mixed clay mycotoxin adsorbent. The in vitro removal efficiencies of the adsorbent for aflatoxin and zearalenone were 100 and 85%, respectively.

Abstract

The invention discloses a preparation method of an illite smectite mixed clay mycotoxin adsorbent. The method comprises the steps of dissolving quaternary ammonium salt with carbon chains with different lengths into a water solution, and then adding illite smectite mixed clay for intercalation reaction; carrying out filter pressing on the product, and drying and grinding to obtain the illite smectite mixed clay mycotoxin adsorbent. The illite smectite mixed clay mycotoxin adsorbent is capable of effectively adsorbing multiple mycotoxins in feed, so that the feed conversion ratio is increased, the feed cost is reduced, and the health of livestock and poultry can be improved.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to a preparation method of an Imon mixed clay mycotoxin adsorbent. Background technique [0002] Mycotoxin is an anti-nutritional factor present in feed and raw materials, and is a highly toxic secondary metabolite of mold. It can cause: acute and chronic poisoning of animals, reduce animal feed intake, reduce animal production performance, feed conversion rate, reproductive performance, and inhibit animal immune function. potential safety hazards. According to the statistics of the Food and Agriculture Organization of the United Nations, about 25% of the grains in the world are polluted by mycotoxins to varying degrees, and 5%-7% of the grains and feeds lose their feeding value due to mildew. In modern farming, the treatment of mycotoxins brings economic losses of hundreds of millions of yuan to livestock and poultry production every year. Therefore, finding a suitable and effectiv...
