Abstract
The paper presented the process of chemical modification of the surface of Kuchak pumice deposit. Grains with sizes from 2,5 to 5 were selected for the modification. Sodium methyl silliconate has been used as a modifier . The surface modification results were confirmed by the IR spectrophotometric method. Due to the modification, the sorbent surface becomes hydrophobic. Water sorption decreases by 60…65 % and oil sorption increases by 25…30 %.
