<p>A method of producing an iodopher powder, characterised in that an organic iodopher-forming compound, in particular polyvinylpyrrolidone, is suspended in a solution of codine dissolved in a solvent in which the iodopher-forming compound is insoluble, and an iodide dissolved in a solvent system, misable with the solvent for the iodine is added, preferably until the iodine solution becomes colourless. The iodine is thus caused to add to the iodopher-forming compound to form the corresponding iodopher in solid form. </p> |
