摘　　要：工业的发展使工业废水排放的增加,工业废水中氟含量影响着环境和人类的正常生活。国家对工业废水的排放做了严格的规定,在水和工业废水处理中,准确测定氟含量具有重要意义。本文采用氟离子选择电极法,结果表明,采用标准曲线法定量,氟离子浓度在0.2-3.0μg/mL的范围内,线性方程为y=-67.354x＋345.74,线性相关系数为0.9994,该方法具有简单、快速、重现性好等优点。Industrial development so that the increased of industrial wastewater discharge industrial wastewater fluoride content affects the environment and human normal life. Discharge of industrial wastewater countries made strict rules,water and industrial wastewater treatment,the accurate determination of fluorine content was important. A method for the determination of fluoride in industrial wastewater by ion selective electrode,the results showed that the F- linear equation was y =- 67. 354 x ＋ 345. 74,and linear correlation coefficient was 0. 9994 in the range of 0. 2 - 3. 0 μg / mL.This method was simple,fast and has the advantage of good reproducibility.
