[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.

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".
