Abstract
Способ получения кристаллического йода из йодсодержащих растворов с большим содержанием органических примесей, при котором обезвоживание и сублимацию йод-пасты осуществляют в две стадии: на первой стадии йод-пасту сублимируют в потоке атмосферного воздуха в присутствии серной кислоты, образующиеся пары йода и йодистоводородной кислоты конденсируют и разделяют. Сконденсировавшийся йод промывают водой, из йодистоводородной кислоты и промывных вод выделяют йод с получением йод-пасты. На второй стадии смесь промытого йода и йод-пасты сублимируют в потоке атмосферного воздуха в присутствии карбоната натрия.
