The invention discloses a novel application of a kudzuvine root powder-based iodine complex in preparation of a medicine for preventing or treating hyperthyroidism. Experimental research shows that compared with a traditional iodine preparation, the radix puerariae powder-based iodine compound can achieve effective loading and stable wrapping of iodine and can effectively reduce the concentration of free iodine, so that the direct stimulation and injury risk of iodine to gastrointestinal mucosa is greatly reduced, the tolerance and compliance of patients taking medicine for a long time are remarkably improved, and the curative effect is good. The medicine is suitable for long-term health management of hyperthyroidism patients, and a novel treatment choice which is safe, stable, convenient and good in tolerance is provided for long-term medicine intervention of hyperthyroidism.

The present invention relates to kits, methods and systems for modulating free iodine in PVP-I, facilitating antimicrobial action while also ensuring compatibility with diagnostic assays.

This application discloses a polarizer and its preparation method, a display module, and a display device, relating to the field of display technology. The polarizer includes a polarizing layer in which perovskite quantum dots are dispersed. The perovskite quantum dots are generated by an in-situ reaction of a perovskite precursor, a ligand solvent, and free iodine ions from the polarizing layer. This application solves the technical problem that residual free iodine ions in the polarizer can easily lead to a decrease in the polarization degree of the polarizer.

This method produces water containing free iodine, which can be used to suppress slime and fouling, without the use of an oxidizing agent. [Solution] By irradiating water containing iodide, such as an aqueous potassium iodide solution (iodide-containing water), with ultrasonic waves using an ultrasonic transducer 31, free iodine is generated in the iodide-containing water.

The present invention discloses a sterilization iodophor compound composition and a processing technology thereof, and relates to the technical field of sterilization, xanthan gum is added into deionized water, stirring is performed until complete dissolution, cooling is performed, glycerol and an amino-polyethylene glycol-polyacrylic acid block copolymer are added, stirring is performed until complete dissolution, povidone iodine is added, stirring is performed until complete dissolution, and the sterilization iodophor compound composition is obtained. And adding the microcapsule solution, adding deionized water, stirring, keeping out of light, standing and filtering to obtain the iodophor compound composition for sterilization. The povidone iodine can oxidize and destroy bacterial protein and nucleic acid by providing free iodine, so that a broad-spectrum bactericidal effect is achieved; thymol and eugenol destroy bacterial cell membranes and cell walls and inhibit key enzyme activity so as to realize a bactericidal effect; tannic acid is combined with protein to form a compound on a cell membrane to destroy the membrane function of the cell membrane; through the synergistic effect of the three components, the sterilization effect of the iodophor compound composition for sterilization is improved.

The invention relates to the technical field of hydrometallurgy and inorganic chemical engineering, and discloses a method for preparing battery-grade high-purity manganese sulfate by reducing manganese oxide ore through sulfur dioxide, a composition is composed of manganese oxide ore powder, water, an iodine source and a fluorosilane modified hydrophobic porous adsorption medium, and the technological process comprises the steps that a gas-liquid-solid-solid four-phase system is constructed, sulfur dioxide is introduced, and a gas-liquid-solid four-phase system is constructed; the elemental iodine enriched on the hydrophobic interface is utilized to preferentially oxidize sulfur dioxide to generate an intermediate reducing agent hydriodic acid, and then manganese ore is leached; along with the reaction, free iodine in a liquid phase is driven to spontaneously transfer into a hydrophobic medium to realize in-situ regeneration by utilizing a high-ionic-strength salting-out effect generated by accumulation of a product manganese sulfate. By means of reaction path reconstruction and physical and chemical environment regulation and control, generation of dithionate by-products is effectively inhibited, the problem of homogeneous catalyst recovery is solved, reaction kinetics and product purity are remarkably improved, and the method is suitable for industrial application.
