摘　　要：选取位于黄土高原中心地区的甘肃陇东北部地区为研究对象,以SPANDS分光光度法测定饮用水中氟的含量,并探讨其分布规律。该地区饮用水主要分为3种类型:水窖水(水窖收集的雨水)、浅井水和深井水,水样总量为127个。试验结果表明,深井水氟含量为1.01～3.95 mg/L,浅井水为1.07～4.60 mg/L,雨水为0.09～1.24 mg/L,无论是深井水还是浅井水,其中氟含量都超过国家饮用水氟标准限值,而80个水窖水样品中,78个符合国家标准。由于受到地质条件和环境因素的影响,3种类型水中氟分布具有相似的规律,即由北向南其浓度逐渐降低。With northern of Longdong District which situated in the central of Loess Plateau,Gansu Province as study object,fluoride concentration in drinking water was determined by using the SPADNS colorimetric method and the distribution law was discussed.Drinking water was classified into three types corresponding to the water from boreholes,shallow wells,and water cellars（water cellar was used to collect rain water） respectively.There were 127 water samples.The results showed that the concentrations of fluoride in the boreholes were varied from 1.01 to 3.95 mg/L,ranging from 1.07 to 4.60 mg/L for the shallow wells,as well as from 0.09 to 1.24 mg/L for water cellars.From the analysis,it was found that the concentrations of fluoride in ground water from either boreholes or shallow wells were above the maximum allowable concentration for fluoride in drinking water of 1.0 mg/L in China,while for the samples from water cellars it was almost lower than the maximum allowable concentration with 78 out of 80.According to the distribution of fluoride,it was obvious that fluoride level in drinking water has integrated strongly to geological form and environmental factors,and their distribution display the similar regularity：their concentration decrease from northern to southern.
