| Abstract: | An on line liquid membrane enrichment flow injection-spectrophotometric method for determination of volatile phenols in water has been developed. A nonpoisonous carrier, tributyl-phosphate (TBP) dissolved in kerosene, was used in the liquid membrane extraction system. Experiment conditions were optimized. Under optimum conditions, the detection limit for volatile phenols is 0.0007 mg/L, the linear range of the determination is 0.001 -0.01 mg/L. The method has been applied to the determination of volatile phenols in tap and river water with satisfactory results. |
