Embodiment 1

[0033] 1) Grinding the montmorillonite produced in Inner Mongolia to 300 mesh, adding water and stirring evenly to make a suspension slurry with a concentration of 10%;

[0034] 2) iron content is the ferric sulfate of montmorillonite weight 1.5%, and the molar ratio is the sodium sulfite of 5 times of ferric sulfate, slowly add in the suspension slurry of step 1) under agitation, pass N 2 Reaction at 50°C for 2 hours;

[0035] 3) centrifugal dehydration of the suspension slurry in step 2);

[0036] 4) Drying and crushing the filter cake obtained in step 3) to 300 meshes to obtain an iron supplement for loaded superfine iron powder.

[0037] The transmission electron microscope observation shows that the average particle size of the ultrafine iron powder supported by montmorillonite is 9nm, and the particle size distribution is between 4nm and 20nm. The content of iron in the montmorillonite is 1.5% by weight.

Embodiment 2

[0039] 1) Grinding the clinoptilolite produced in Jinyun, Zhejiang to 400 mesh, adding water and stirring evenly to make a suspension slurry with a concentration of 1%;

[0040] 2) Ferric chloride with an iron content of 5% by zeolite weight, and sodium bisulfite equimolar with ferric chloride are slowly added to the suspension slurry of step 1) under stirring, and the nitrogen 2 Reaction at 100°C for 10 hours;

[0041] 3) the suspension slurry in step 2) is filtered and dehydrated;

[0042] 4) Drying and crushing the filter cake obtained in step 3) to 500 meshes to obtain an iron supplement for loaded superfine iron powder.

[0043] The transmission electron microscope observation shows that the average particle size of the zeolite-loaded ultrafine iron powder is 14nm, and the particle size distribution is between 6nm and 25nm. The content of iron in the zeolite is 5% by weight.

Embodiment 3

[0045] 1) Grinding a commercially available ZSM-5 zeolite molecular sieve to 500 mesh, adding water and stirring evenly to make a suspension slurry with a concentration of 5%;

[0046] 2) Ferric nitrate with an iron content of 10% by weight of the zeolite, and potassium borohydride with a molar ratio of 0.5 times the ferric nitrate are slowly added to the suspension slurry in step 1) under stirring, and the N 2 Reaction at 80°C for 5 hours;

[0047] 3) the suspension slurry in step 2) is filtered and dehydrated;

[0048] 4) Drying and crushing the filter cake obtained in step 3) to 500 meshes to obtain an iron supplement for loaded superfine iron powder.

[0049] The transmission electron microscope observation shows that the average particle size of the zeolite-loaded iron powder is 34nm, and the particle size distribution is between 20-55nm. The content of iron in the zeolite is 10% by weight.

Abstract

An iron supplement used for the forage of animals and fowls and human health-care food or medicine is a porous mineral material carried superfine Fe powder. It is prepared through providing mineral material as micro reactor and reducing the Fe salt to obtain superfine Fe powder.

Description

technical field [0001] The invention relates to an iron supplement for loaded superfine iron powder, its preparation method and use, in particular to an iron supplement for superfine iron powder loaded with porous mineral materials, its preparation method and its use. Background technique [0002] Iron is an essential trace element for animals. It is an essential component of hemoglobin and myoglobin. The activity of oxidase is closely related. Iron participates in the normal transport of oxygen in body tissues, directly affects the energy and protein metabolism of the body, and also affects the immune function and reproductive performance of animals. The iron content in conventional feed is relatively high, and in terms of quantity alone, it can already meet the needs of animals. However, the utilization rate of iron in plant feed is extremely low, and the degree of intensification of the breeding industry is getting higher and higher. The efforts in both breeding and nut...
