Abstract
A process for the recovery of iodine from mother liquors or wastes containing iodinated organic compounds, by mineralisation of organic iodine and subsequent transformation of the formed iodide into elementary iodine, characterized in that the aqueous solution is concentrated to a suitable volume before the mineralisation step, under atmospheric pressure and at the boiling temperature, and said solution is purified by nanofiltration.
