Аннотация: Abstract—A sorbent of oil and water-dissolved oil components is prepared from organobentonite, and its ability to absorb those products is assessed. Bentonite modified with dodecyltrimethylammonium added at a rate of 0.5 CEC was found to absorb 1.6 times as many oil components as nonmodified bentonite. The obtained sorbent has good flotage characteristics due to the formation of a durable film on the surface of oil spots, which can be easily removed. The sorbent is effective in extracting water-soluble oil compounds and has no toxic effect on Paramecium caudatum and Ceriodaphnia affinis. When the temperature is lowered from 22 to 10°, sorbent efficiency is reduced.
