The use of melts in various fi elds of industry and scientifi c research is based on the study of the properties of melts and the chemical processes occurring in them. In modern engineering and technology, a signifi cant number of processes are associated with the use of mixtures of lithium and sodium halides as mixtures that accumulate heat, as electrolytes for medium-temperature chemical current sources. Therefore, the interest in the study of systems involving such systems is continuously increasing.

New way, allowing extract the iodine from natural sources without their preliminary acidification, is described in the paper. The method is based on using the ion reactions and method of liquid-phases emulsion membrane extraction, with using quaternary ammonium compounds as extragent of iodide. Experimental data, gotten in the course of undertaking work, enable to application of the described technology to production.
