Abstract
Preliminary birch bark activation by steam under the conditions of explosive autohydrolysis was studied. It has been established that as the result of the preliminary processing the sorption activity of obtained enterosorbents with respect to methylene blue and gelatin exhibits a significant increase. The properties of enterosorbents resulted from autohydrolyzedyh phloem and silver birch bark have been compared. Conditions for the activation of birch bark by explosive authohydrolysis to obtain enterosorbents have been determined those could be better than commercial enterosorbent Polyphepan according to the sorption activity with respect to methylene blue and gelatin.
