Problems solved by technology

However, its production process is not yet mature
The main reason is: the concentrated acid used in the production process, especially after the concentrated sulfuric acid is added, and then the concentrated phosphoric acid is added, a large amount of heat is generated instantly, which causes the production raw materials to agglomerate due to strong heat, making it difficult to continue the production smoothly; High pressure and heat resistance requirements for production equipment

[0028] 1.3 Preparation of iodic acid solution

[0029] Raw material ratio: total iodine 3%, iodide 0.4%-1%, surfactant 20%-30%, phosphoric acid (85%) 9%-16%, sulfuric acid (98%) 14%-28%, and The total amount of the phosphoric acid and the sulfuric acid is 30% by weight-37% by weight;

[0030] Add raw material iodine, iodide, non-ionic surfactant in turn according to the ratio of raw materials, then shake well, mix well, let it complex for 30 minutes; then add acid, stir evenly; acid, after cooling, add the rest of the water. The whole process should be carried out under the condition of constant stirring.

[0031] 1.4 Determination of available iodine content

[0032] Accurately weigh about 10g of this product, put it in an iodine measuring bottle, add 50ml of water, and titrate it with sodium thiosulfate titration solution (0.1mol / L) until it becomes colorless. Every 1ml of sodium thiosulfate titration solution (0.1mol / L) is equivalent to 12.69mg of iodine.

[0033] ...

Embodiment 1

[0066] First, take 3kg of iodine and 0.4kg of potassium iodide, add 20kg of NP-10 (nonylphenol polyoxyethylene ether), and fully dissolve in the stirring tank for 30 minutes. Then add 28kg of sulfuric acid (98%), stir well until the mixture is uniform, then add 20kg of water, stir until the solution is cooled, then add 9kg of phosphoric acid (85%) under constant stirring, mix thoroughly for 1 hour, add water to 100kg, and stir evenly After that, the product is obtained. The obtained product has no insoluble precipitate after aging, and the solution is uniform and stable. After analysis, its available iodine content is 2.8%, and its relative density is 1.171, which meets the requirements of the relevant national standard "Standards for Imported Veterinary Drugs".

Embodiment 2

[0070] First, take 3kg of iodine and 0.7kg of potassium iodide, add 25kg of NP-10 (nonylphenol polyoxyethylene ether), and fully dissolve in the stirring tank for 30 minutes. Then add 12.5kg of phosphoric acid (85%), stir well until the mixture is uniform, then add 30kg of water, stir until the solution is cooled, then add 21kg of sulfuric acid (98%) under constant stirring, mix thoroughly for 1 hour, add water to 100kg, and stir After uniformity, the product is obtained. The obtained product has no insoluble precipitate after aging, and the solution is uniform and stable. After analysis, its available iodine content is 2.78%, and its relative density is 1.169, which meets the requirements of the relevant national standard "Standards for Imported Veterinary Drugs".

Abstract

The invention relates to an iodic acid solution for aquaculture. The iodic acid solution comprises the following components by weight percent: 3% of iodine, 0.4-1% of iodide, 20-30% of nonionic surfactant, 9-16% of phosphoric acid with the concentration of 85%, 14-28% of sulfuric acid with the concentration of 98% and the balance of water, wherein the total weight percent of phosphoric acid and sulfuric acid is 30-37%. The invention further relates to a preparation method of the iodic acid solution for aquaculture. The iodic acid solution for aquaculture is smart in design, high in stability and good in sterilization effect, reduces the waste of production cost due to volatilization of a large amount of iodine, is prepared by a step feeding method, is simple and convenient to operate and reasonable, lowers the pressure-resistant and heat-resistant requirements on production equipment, reduces the production cost, and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the technical field of disinfectants, in particular to the technical field of compound iodine solution, in particular to an iodic acid solution for aquaculture and a preparation method thereof. Background technique [0002] The iodic acid solution used in aquaculture is an aqueous solution made of iodine, iodide, nonionic surfactants, phosphoric acid, and sulfuric acid. With the increasing scale and intensification of aquaculture, the stocking density of aquaculture animals is increasing, resulting in higher and higher incidence of aquaculture animals, and more and more complicated diseases, and some are even difficult to control. It is an effective measure to control aquatic animal diseases to use safe and efficient disinfectants to kill pathogens in water and on the surface of farmed animals, so as to cut off the spread of pathogens. [0003] With its safety, broad-spectrum, high efficiency and quick-acting advantages, iodic...
