摘要
The new combined method of the online liquid membrane enrichment flow injection of 4-amino-antipyrine(4-AAP) and spectrophotometric determination of volatile phenols in water has been developed.A flow carrier,tributyl phosphate(TBP) dissolved in kerosene,was used in the liquid membrane extraction system.Experiment conditions were optimized.Under optimal conditions,the detection limit for volatile phenols is 0.5 μg/L and the linear range of the determination is 1mg/L～100μg/L.The method has been applied to the determination of volatile Phenols in tap,river and industrial waste water with satisfactory results.
