【 摘 要 】

The sorption properties of mesoporous coals (pore size of ∼ 4 nm, the specific surface area of 25 to 150 m2/g) of Georgian hard coal deposit have been studied and the efficacy of their usage for the treatment of sewage water polluted by oil products has been established. Purification rate depends on coal mass loaded in filter, grain size, initial concentration of oil products, the water acidity, etc.
