Dibutyl phthalate (DBP) is a kind of important enivronmental hormone.Under basic conditions,the fluorescence of DBP has been studied.the effect of the reaction media and temperature on the fluorescent intensity has also been studied.The determination method of DBP in water samples by fluorscent spectrophotometry is established.The tests showthat under basic conditions,when the concentration of DBP is between 0.1-7.0 mg/L,the flourescent intensity of DBP is linear with the concentration of DBP.The minimum detection limit of this method is 0.1 mg/L.The recovery rate is between 96.67% to 104.00%.It is simple,rapid and highly sensitive.Satisfactory results have been obtained in the determination of DBP in actual water samples.
