Problems solved by technology

However, the existing disinfectant products generally have a low distribution coefficient and cannot meet the requirements of relevant national standards (such as "Standards for Imported Veterinary Drugs"), and the distribution coefficient is a very key indicator of this type of disinfectant products

[0027] 1.3 Preparation of compound iodine solution

[0028] Add raw material iodine 1.8%-3%, iodide 0.3%-1%, non-ionic surfactant 15%-30%, then shake well, mix well, let it complex for 30min; then add hydrochloric acid (75%) 3.5 -4.5%, stir evenly; add a part of water, stir evenly, add phosphoric acid (85%) 16%-26%, stir quickly, wait for it to cool, add the rest of water, mix evenly to get the finished product.

[0029] 1.4 Determination of available iodine content

[0030] 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 0.1269mg of iodine.

Embodiment 1

[0073] First, take 2kg of iodine and 0.3kg of potassium iodide, add 15kg of NP-10 (nonylphenol polyoxyethylene ether), and fully stir and dissolve in the stirring tank for 30 minutes. Then add 3.5kg of concentrated hydrochloric acid, stir well until the mixture is uniform, then add 20kg of water, stir until the solution is cooled, then add 26kg of phosphoric acid under the condition of constant stirring, mix thoroughly for 1 hour, then add water to 100kg, after stirring evenly, the product is obtained. After analysis, the distribution coefficient of this solution is 390, and the available iodine content is 1.82%, which meets the requirements of the relevant national standard "Standards for Imported Veterinary Drugs". After the stability accelerated test, the loss rate of available iodine is 2%, and the stability is good.

Embodiment 2

[0077] First, take 2kg of iodine and 0.5kg of potassium iodide, add 20kg of NP-10 (nonylphenol polyoxyethylene ether), and fully stir and dissolve in a stirring tank for 30 minutes. Then add 3.5kg of concentrated hydrochloric acid, stir well until the mixture is uniform, then add 20kg of water, stir until the solution is cooled, then add 26kg of phosphoric acid under the condition of constant stirring, mix thoroughly for 1 hour, then add water to 100kg, after stirring evenly, the product is obtained. After analysis, the distribution coefficient of this solution is 300, and the available iodine content is 1.89%, which meets the requirements of the relevant national standard "Standards for Imported Veterinary Drugs". After the stability accelerated test, the loss rate of available iodine is 3.5%, and the stability is good.

Abstract

The invention relates to an aquaculture compound iodine solution. The solution comprises the following components in percentage by weight: 1.8-3% of iodine, 0.3-1% of iodide, 15-30% of a nonionic surfactant, 3.5-4.5% of hydrochloric acid with the concentration of 75% by weight, 16-26% of phosphoric acid with the concentration of 85% by weight and the balance of water. The invention further relates to a preparation method of the aquaculture compound iodine solution. The aquaculture compound iodine solution is ingenious in design, has high distribution coefficient and high stability 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 a compound iodine solution for aquaculture and a preparation method thereof. Background technique [0002] The compound iodine solution used in aquaculture is an aqueous solution made of iodine, iodide, non-ionic surfactant, hydrochloric acid and phosphoric acid. With the increasing scale and intensification of aquaculture, the stocking density of aquaculture animals is increasing, resulting in higher and higher morbidity rates and more complex diseases of aquaculture animals, and some even become 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] Compound iodine solution has gradually become the preferred disinfectant in ...
