摘　　要：建立了一种新的荧光光度法分析水中痕量酚。水中的酚经紫外光照射后,激发强荧光(λ_(ex)=273nm;λ_(em)=302nm),能直接进行荧光光度测定。检出限0.03μg/L,相对标准偏差0.28%,回收率97.4%～102.3%,方法简单快速,精密度和准确度高、无毒、安全。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.
