Embodiment example 1

[0028]Embodiment 1 Case: Weigh 100g attapulgite, pulverized to homogeneity using a grinding machine, through 300 mesh sieve, was added 500mL of water slurried, followed by addition of 10mmol / L citric acid in 240mL modified with a magnetic stirrer at after stirring for 8h at room temperature through a 200 mesh sieve to remove impurities, in hypoxic environment calcined at 300 ℃ acidified to give a modified attapulgite, through a 200 mesh sieve to obtain an acid-modified attapulgite powder. Weighed lanthanum oxide, cerium oxide, samarium oxide, the 30g, was added 500mL of 10mmol / L hydrochloric acid sufficient reaction 8h, filtered to remove impurities to prepare lanthanum, cerium, samarium rare earth ion modifier. Attapulgite powder and the above rare earth ions Modifier 1: 1 mixed, evaporated to dryness, in hypoxic environment 200-500 deg.] C to obtain calcined attapulgite modified rare earth element compound, followed by using a sufficient amount of deionized water, washed wit...

Embodiment example 2

[0029] Embodiment 2 Case: Weigh 100g attapulgite, pulverized to homogeneity using a grinding machine, through 300 mesh sieve, was added 500mL of water slurried, followed by addition of 180mL of 10mmol / L 4- phenyl-butyric acid modification, after stirring for 8h using a magnetic stirrer over a 200 mesh sieve to remove impurities at room temperature, in a hypoxic environment calcined at 300 ℃ to give 4-phenylbutyric acid modified attapulgite, through a 200 mesh sieve to obtain an acid-modified attapulgite powder. Lanthanum oxide sufficiently weighed 100g, was added 500mL of 10mmol / L hydrochloric acid to 4h, filtered to remove impurities, to obtain a lanthanum ion modifier. Attapulgite powder and the above rare earth ions Modifier 1: 1 mixed, evaporated to dryness, in hypoxic environment 200 ℃ obtained by firing the lanthanum ion modified attapulgite, and then using a sufficient amount of deionized water, ethanol washed three times each, and dried at 50-90 deg.] C 4h, ground to p...

Embodiment example 3

[0030] Embodiment 3 Case: Weigh 100g attapulgite, pulverized to homogeneity using a grinding machine, through 300 mesh sieve, was added 500mL of water slurried, followed by addition of 10mmol / L 480mL of acetic acid modification with a magnetic stirrer at room temperature after stirring for 8h under 200 mesh sieve to remove impurities, in a hypoxic environment to obtain calcined at 300 ℃ acid modified attapulgite, through a 200 mesh sieve to obtain an acid-modified attapulgite powder. Weigh sufficient terbium oxide, lutetium, scandium the 30g, was added 500mL of 10mmol / L, sulfuric acid reaction 4h, filtered to remove impurities to prepare terbium, lutetium, scandium ion modifier. Attapulgite powder and the above rare earth ions Modifier 1: 1 mixed, evaporated to dryness, in hypoxic environment 200 ℃ obtained by firing terbium, lutetium, scandium complex of the rare earth element-modified attapulgite, and then use the foot amount of deionized water, washed with ethanol three tim...

Abstract

The invention discloses a preparation method of an attapulgite feed additive with mycotoxin adsorption and bacteriostasis functions. The preparation method comprises the following steps that acid modification treatment is carried out on attapulgite, impurities are purified, a compound rare earth element ionic surfactant prepared in advance is added, reacting is carried out at 50-90 DEG C for 8 hours, a product is precipitated, roasted, washed, dried, crushed and sieved, the rare earth modified attapulgite feed additive has mycotoxin adsorption and bacteriostasis functions and further can regulate body metabolism is obtained, and the rare earth modified attapulgite feed additive can be applied to livestock and poultry feed addition to improve intestinal health of livestock and poultry.

Description

Technical field [0001] The present invention relates to the preparation method of a rare earth-modified embossed stone feed additive, which belongs to the field of economic ore deep processing. Background technique [0002] Mold toxin's contamination of feed and raw materials is a global problem, vomiting toxin (also known as deoxyxecoxykenyl alcohol, DEOXYNIVALENOL, DON) is the most representative of a class of B-type single-endone toxins, easy Growth and storage of feed feed materials such as corn, wheat. The chemical properties of vomiting toxins are very stable. The response measures adopted for the contamination of feed raw materials that have existing feed raw materials include: add non-nutritional adsorbent, microbial degradation, chemical heterogeneous modification, biological enzymes and raw materials dilution. Various biological degradation and chemical modification methods have problems with demanding reaction conditions in the process of use, and the effect is unstabl...
