By. the end of the hydropig over the Kir lot is drained, the cqp6eHt is flushed with water and dried.: EXAMPLE 4. The cotton and nionionoaa are heat treated in hermetically sealed containers for 35 minutes, after which the rest of the aeloil material is washed down to Mofy LA : 1 solution of 2.5N hydrochloric acid and is subjected to hydrolysis in the presence of 70% dimethylsulphide for 15 mVv at 1 O5 106 ° C. At the end of the hydrolysis, the acid is drained, the sorbent is washed with R and dried. As can be seen from the above data, the yield of the sorbent obtained by the proposed method is the raw material. In addition, the sorbent, obtained by whom by the proposed method, significantly has such indicators as speed and sectional capacity, and the content of impurities is insignificant in terms of: the ratio with the sfbentom. The sorbent content is characterized by the relative weight of Wioe, occupied by one gram of cq; obtained by the proposed method is also higher. Ryo; The benefits are given in the table. 7615 The whole complex of these properties allows one to widely use the sorbent obtained by the proposed method in various sectors: for cleaning gases from water and highly dispersed impurities; As a carrier in the analytical determination of substances by chromatography, etc. Formula of the Invention A method for producing a sorbent based on microcrystalline cellulose by thermally treating a cellulose at 19 O-250 C followed by hydrochloric acid, washing and drying, so that, in order to increase the yield and quality of the sorbent, the treatment with hydrochloric acid is carried out in the presence of 4–70% dimethyl sulfoxide.
