Abstract

In extracting phenols from waste aqueous liquors by means of a solvent, the liquors are, before admixture with the solvent, treated with active carbon or a substance, such as brown coal ash, containing active carbon. Oily and solid matter may be preliminarily removed from the waste liquors by filtration or treatment with gases.ALSO:In extracting phenols from waste aqueous liquors by means of a solvent, the liquors are, before admixture with the solvent, treated with active carbon or a substance, such as brown coal ash, containing active carbon.
