| A method has been proposed for the use of Estsorb as a sorbent for removal of phenols from wastewater of shale oil chemicals production. A preliminary study has been made to determine the conditions required for the wastewater treatment. It is shown that at the initial concentrations of shale oil phenols within the range of 100-350 mg·l –1, a water purification efficiency of 92-96 % can be reached. |
