Abstract: Phenol was extracted from sebacic acid wastewater (SAWW) using liquid-liquid extraction in batch as well as serial modes by applying different solvent: SAWW (1:250 - 5:250, v/v). Alcohols (1-hexanol, 1-heptanol, and 1-octanol), castor oil and Aliquat-336® were used for phenol extraction. In a typical extraction experiment involving shaking and allowing for phase separation, phenol (75-96%) can be extracted with different solvents using solvent-wastewater ratio (5:250 v/v). Generally, extraction (%) increased with solvent ratio; however, chain length of alcohols did not affect extractability of phenol much. Best extraction of phenol occurred into Aliquat 336.
