Abstract

The laws sorption ascorbic acid on klinoptilolite tuf are revealed at temperature 293 T at
pH=5,60, interactions, caused by various types of interactions in system sorbent – water - vitamin C,
which include ion exchange, formation aqua-complex and association of ascorbic acid molecules.
Distribution coefficient of an acid between phases of a solution and klinoptilolits is calculated. Is marked,
that the distribution of vitamin C in a structural sorbent matrix results to the dehydration.
