Abstract
A new spectrofluorimetric detemination of trace phenol in water was proposed in this paper.Phenol emit fluorescence under the irradiation of ultraviolet light.The excitation and emission wavelenths of phenol are 273nm and 302nm respectively.On this basis phenol can be detected directly by spectrofluorimetry.The detection limit is 0.03μg/L the relative standard deviation is 0.28%(n=11)and the recovery is 97.4~102.3%.The methodis simple ropid precise and accurate.
