The invention relates to a process for the recovery and recycling of the iodine from aqueous solutions comprising iodine-comprising aromatic compounds in which the iodine contained in said aromatic compounds is directly converted into molecular iodine at a pH lower than 1, in the absence of a catalyst.

The present invention relates to a process for obtaining and refining elemental iodine contained in an iodide solution, which specifically comprises the steps of iodide cutting, and iodine melting, which take place simultaneously by reacting the preheated iodide solution with an oxidizing agent for directly producing elemental molten iodine, without passing iodine through a crystalline state; and the step of separating elemental molten iodine from spent melt water by liquid-liquid separation; carrying out all these steps in a single system operated in continuous regime.

In a system and method for disinfecting a surface of an object with iodine-laden gas, a carrier gas generation means generates a gas stream, which is then directed into a chamber that includes an iodine source. As the gas stream enters and passes through the chamber, iodine is drawn and absorbed into the gas stream, creating an iodine-laden gas that exits the chamber. The carrier gas stream is humidified prior to or after its interaction with the iodine source. In some embodiments, the iodine-laden gas then travels from the chamber and is directed into an enclosure when it interacts with microbes contained on a surface of an object housed within the enclosure or otherwise engaged by the enclosure. In other embodiments, as the iodine-laden gas exits the chamber, it is directed to a nozzle, via which the iodine-laden gas is applied to the surface of the object to be disinfected.
