METHOD OF OBTAINING ANION-EXCHANGE CELLULOSE-BASED MATERIALS (VERSIONS) AND APPLICATION OF OBTAINED MATERIAL FOR CONCENTRATION OF ANIONIC FORMS OF ELEMENTS FROM SOLUTIONS Russian patent published in 2009 - IPC C08B15/06 

FIELD: chemistry.

SUBSTANCE: invention relates to method of obtaining cellulose-based materials for concentration for analytical purposes of anionic forms of elements from solutions. Cellulose, preliminarily mercerised with water-alcohol alkali, is subjected to epoxidation with epichlorhydrine in presence of 15-crown-5 with further aminating with aliphatic amines with heating. In one of method versions aminating with further washing with alkali is performed, in other version catalytic quantities of water are added into respective amine. Claimed method is simple and safe. Obtained material can be used both in form of salt and in form of base.

EFFECT: elaboration of simple and safe method of obtaining cellulose-based materials for concentration for analytical purposes of anionic forms of elements from solutions.
