Abstract: . Phenol in wastewater causes adverse pollution problems and could affect aquatic and human life. Emulsion liquid membrane (ELM) had a high potential possibility to extract phenol from wastewater. The new ELM formulation that consists of Tributyl phosphate (TBP) and Di-(2-ethylhexyl) phosphoric acid (D2EPHA) in kerosene as a synergistic carrier is investigated. Several operating parameters affecting the phenol extraction and stability of W/O/W emulsion through breakage or swelling were studied, such as extraction time, agitation speed, and treat ratio. At the optimum condition of a treat ratio of 1:5, an agitation speed of 300 rpm, and an extraction time of 3 minutes, a stable ELM process yielded an 89 % phenol extraction. This research highlights the potential synergistic effect of the ELM formulation of the TBP-D2EHPA system in enhancing emulsion stability and improving phenol extraction efficiency.
