METHOD OF OBTAINING NANOCOMPOSITIC SORBENT FOR DRYING SOILS Russian patent published in 2017 - IPC B01J20/30 C09K17/48 B01J20/26 B01J20/12 

FIELD: chemistry.

SUBSTANCE: sorbent is produced by initiating radical polymerization of acrylic monomers in the presence of bentonite in an aqueous medium with stirring. The monomer mixture consisting of acrylamide, dimethylacrylamide and acrylic acid, previously neutralized with an aqueous solution of potassium and ammonium hydroxides, is subjected to polymerization. Alikarboxycellulose is additionally introduced into the mixture of monomers. As a polymerization initiator, a redox system consisting of ammonium persulfate and tetramethylethylenediamine is introduced into the mixture. The process is carried out with stirring at a speed of 300-500 rpm at 30-45°C.

EFFECT: invention makes it possible to obtain a sorbent with improved characteristics.
