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.

Currently iodine defi ciency diseases are one of the most important medical and social problems. In this regard, the purpose of the study is to determine the content of iodine, iodides, iodates in iodized salt, drinking and mineral water, seaweed, to determine the stability of the iodine content in salt. For the qualitative determination of iodides and iodates ions in salts and molecular iodine in seaweed, an iodine starch reaction has been carried out.

В работе представлены и обсуждены результаты изучения
влияния природы и свойств растворителя на экстракцию йода
из различных йодсодержащих источников. В качестве способа
извлечения йодид-иона предлагается метод ионного обмена в со-
четании с жидкофазной эмульсионной мембранной экстракцией.
Полученные данные позволяют сделать обоснованный выбор за
систему экстрагент – растворитель.
