Example Embodiment

[0010] Example 1

[0011] 1) The depolymerized, dispersed, separated and purified montmorillonite mineral, together with 15% sodium chloride equivalent to the weight of the mineral, add water and stir evenly to make a suspension slurry with a concentration of 20%, and wash it for 5-7 times until there is no Cl - , Use a 0.1mol / L nitrate solution to detect no white precipitation, and remake a slurry with a concentration of 10% with water; 2) Add chitosan equivalent to 5% of the mineral weight in the slurry under high-speed stirring, and continue to stir the reaction For 20 hours, the reaction temperature was 95°C, then aged at 50°C for 7 days, washed with water 5 times, and centrifuged for dehydration;

[0012] 3) The filter residue is dried under vacuum at less than 80°C and pulverized by a jet mill dry method.

[0013] 4) The in vitro adsorption rates of lead, cadmium, arsenic, mercury, nickel, tin and antimony on the nano feed additives prepared as described above are 99.0%, 90%...

Abstract

The preparation method of nano feed additive capable of reducing heaving metal residue in animal product, poultry product and aquatic product incldues the following steps: (1). uniformly stirring nano montmorillonite and sodium chloride by adding water to make them into ore pulp, washing with water to obtain ore pulp; (2) adding chitosan, stirring to make reaction, ageing, washing with water and dewatering; and (3), filtering and removing residue, drying and pulverizing. Said additive can make broad-spectrum absorptino of the elements of lead, cadmium, arsenic, mercury, nickel, tin and antiomony, its specific area is large and adsorptivity is strong.

Description

technical field [0001] The invention relates to a preparation method of a nano feed additive for reducing heavy metal residues in livestock, poultry and aquatic products. Background technique [0002] Animal husbandry has always been an important pillar industry of my country's agriculture. With the guidance of the market economy and the popularization and application of breeding science and technology, my country's livestock, poultry and aquatic products are abundant, and the situation of oversupply appears from time to time. The livestock product market has shifted from a seller's market to a buyer's market, and from quantity-based to quality-based consumption. In this situation, the safety of livestock, poultry and aquatic products has become the focus of attention. Residues of harmful substances in animal products are becoming more and more serious, posing a threat to human health. Furthermore, after my country's accession to the WTO, tariffs ...
