Abstract

1492606 Removing phenols from wastewater COMMISSARIAT A L'ENERGIE ATOMIQUE 29 Nov 1974 [30 Nov 1973] 51720/74 Heading C lC Phenols are removed from aqueous waste liquors containing them by (a) extracting at an acid pH with an organophosphate solvent diluted in a hydrocarbon, (b) extracting the phenols from the solvent with alkali solution, (c) precipitating phenols from the resultant phenate solution by the addition of acid and (d) separating the solution from the phenols. The acid solution from (d) is preferably recycled to a point upstream of stage (a). The specified organophosphate is tributyl phosphate diluted in n-heptane.
