THE FORMATION OF SUSPENSION IN THE EXTRACTION SYSTEM «SLIGHTLY ACIDIC SOLUTION OF NITRATE Ln - COMMERCIAL D2EHPA - ALIPHATIC DILUENT»

Stable suspension was found to form in extraction of Ln by commercial D2HEPA, precluding emulsion splitting. The suspension has the form of amorphous solid phase, containing di-(2-ethylhexyl)phosphate-ions and neutral organic substance apart from Ln. There have made a guess that formation liquid crystal causes of appearance those suspensions.
