Problems solved by technology

However, as far as the current situation of bait additives is concerned, some bait additives with high technical level and the ability to promote fish growth have yet to be developed.
In addition, the carrier of the existing essential trace element bait additives needs to be improved, for example, the carrier of the essential trace element of some additives contains inorganic acid radicals
Sulfate radicals have been found to have a stimulating effect on the intestinal tract, which not only affects the absorption function, but also brings other side effects

Embodiment 1

[0020] Accurately weigh 0.010 mol of zinc carbonate, 0.045 mol of lanthanum carbonate and 0.290 mol of glutamic acid, respectively. After mixing zinc carbonate and lanthanum carbonate, add water and stir to form a suspension. The above suspension was placed on a magnetic stirrer, stirred and heated to keep the temperature constant at 50 °C. Add the glutamic acid aqueous solution dropwise to the mixed suspension of zinc carbonate and lanthanum carbonate. Glutamic acid reacts with excess zinc carbonate and lanthanum carbonate to form the corresponding glutamic acid complex. During the reaction, carbon dioxide bubbles escape constantly, and when the carbon dioxide bubbles stop escaping, the reaction is continued to ensure that the above reaction is carried out completely. The reaction time is controlled at 1.5h. After the reaction is completed, the excess solvent water is evaporated to precipitate the target product, aged, filtered, and naturally dried in the air to obtain the...

Embodiment 2

[0022] Accurately weigh 0.100 moles of zinc carbonate, 0.450 moles of lanthanum carbonate and 2.900 moles of glutamic acid. The reaction temperature was 60°C. All the other operations are the same as in Example 1. The molecular formula of gained target product is: Zn 0.1 La 0.9 L 2.9 , and its yield was 92.6%.

Embodiment 3

[0024] Accurately weigh 0.100 moles of zinc carbonate, 0.450 moles of lanthanum carbonate and 2.900 moles of glutamic acid. The reaction time is 2.5h. All the other operations are the same as in Example 1. The molecular formula of gained target product is: Zn 0.1 La 0.9 L 2.9 , and its yield was 91.5%.

Abstract

The invention discloses a series of composite zinc rare earth complex fish bait additive and process for preparation, which is complex of zinc, rare earth and biomolecular glutaminic acid having the chemical formula of ZnxLn(1-x)L(3-x), wherein Ln is La, Ce, Pr, Nd or Sm, L- is glutaminic root, 0.1<=x<=0.4. The preparation process mainly comprises the steps of weighing, mixing, obtaining mixed liquid suspension, stirring the mixed liquid suspension of zinc carbonate and rare earth carbonates at 50 deg. C - 60 deg. C, dropping the water solution of glutamic acid into the mixed liquid suspension, evaporating water, evoluting destination product, ageing, filtering, air-drying or drying through infrared lamp kilning method.

Description

technical field [0001] The invention belongs to fish bait additives, in particular to a series of compound zinc rare earth complex fish bait additives. [0002] The invention also relates to a preparation method of the fish bait additive. Background technique [0003] Diet composition is closely related to human health. Compared with foreign countries, the dietary composition of our country has a high content of plant foods, while the consumption of animal foods needs to be increased urgently. Obviously, the development of fish farming is very important to optimize the dietary composition of our people, and high-efficiency fish bait is a necessary condition for the development of fish farming. At present, my country's feed industry is in urgent need of vigorous development, and the situation that some high-efficiency feeds still rely on foreign countries must be changed quickly. The development of high-efficiency feed with my country's own intellectual property rights can...
