Article Preview

Removal of phenol from aqueous solution by a new emulsion liquid membrane (ELM) system and its heat-induced demulsification have been investigated. The ELM consists of commercial kerosene as organic solvent, OP-4 as surfactant agent, hydrochloric acid as the stripping phase. Effect of different operating parameters such as internal phase concentration, surfactant concentration, stirring speed, PH value in external phase, volume ratio of membrane phase to internal phase and volume ratio of membrane phase to external phase were investigated for the removal of phenol from aqueous solution. At the optimum condition about 95.7% phenol is removed in less than 20min of contact time. The demulsification efficiency was investigated under different temperature and time and proved to be high at 80°C.
