Problems solved by technology

Because of this, according to in vitro evaluation experiments and animal feeding effect experiments, montmorillonite and other smectite minerals have a good adsorption effect on polarly charged mycotoxins (such as aflatoxin, etc.), Less polar mycotoxins such as ketene, deoxynivalenone (macromolecular trichothecenes) are poorly absorbed

Abstract

The invention discloses a preparation method and application of modified magnesium lithium silicate, and the preparation method comprises the following steps: taking a beryllium-containing substance, a magnesium salt, a lithium salt, silica sol and the like as raw materials, and carrying out high-temperature hydrothermal reaction to prepare magnesium lithium silicate; the number of charges of the crystal lattice structure is large, and the mycotoxins with small polarity such as zearalenone and vomitoxin can be effectively adsorbed in an electrochemical adsorption mode, so that the application prospect in the industry of preventing and treating the mycotoxins by feed is extremely wide.

Description

technical field [0001] The invention relates to the field of preventing and treating mycotoxins in feed, in particular to a preparation method and application thereof for mycotoxins with a large amount of charge, good adsorption performance and a wide prevention and control range. Background technique [0002] The pollution of mycotoxins in feed and the harm it causes are quite serious, and have brought serious consequences on a global scale (according to statistics, 70% of feed samples worldwide have mycotoxins exceeding the standard). my country's existing feed production is more than 200 million tons, ranking among the top five in the world. The rainy season and summer in many areas of my country (especially in South China) are quite humid, leading to moldy feed and mycotoxin contamination are very common, and the resulting harm is already a big problem. Among the hundreds of mycotoxins found so far, several mycotoxins such as aflatoxin, ochratoxin, deoxynivalenol, and z...
