Abstract
To reduce the toxic load on the body of animals and the accumulation of heavy metals in livestock products, the use of sorbents of various origins is effective. Natural substances, which, along with sorption, have anticarcinogenic, antimutagenic, immunomodulatory properties and antitoxic activity are of particular interest. Sorption properties of the birch fungus Inonotus obliquus (chaga, or chamfered tinder) with respect to cadmium and lead were determined in an experiment on model solutions in order to assess the possibility of its further use as an enterosorbent to reduce the negative effect of heavy metals on the animal body. Under in vitro conditions, the maximum sorption by chaga from aqueous solutions of lead reached more than 95 % of cadmium – up to 89 %. The natural zeolite of the Shivyrtuiskoye deposit was used as a reference preparation. It has been established that the sorption efficiency of both chaga and shivyrtuin with respect to lead is higher than with respect to cadmium. At the same time, chaga sorbed lead worse than shivyrtuin (by 29,4 %), and cadmium more efficiently (by 28,0 %).
