| 摘 要： | 采用离子选择电极法对生活饮用水中氟化物浓度进行了测定。讨论了水样中pH值、温度、响应时间对测定结果的影响。在最佳条件下，方法的线性范围为0．10～3．0mg／L，相关系数为0．9999，检出限为0．05mg／L，实际水样加标回收率为97％～106％，相对标准偏差（n=5）为0．04％～0．65％。方法简单快速，干扰小，重现性好，加标回收率令人满意，能进行生活饮用水中氟化物浓度的有效测定。

| Abstract: | A method for determination of fluoride in drinking water determined by ion selective electrode method was assessed. The influences of pH value of water samples, temperature, response time on results were discussed. Under the optimized condition, the linearity of the method was ranged from 0.10 to 3.0 mg.L-1, with a correlation coefficient of -0.9999. The limit of detection was 0.05 mg.L-1. The recoveries of real water samples were 97~106% with the relative standard deviation of 0.04~0.65% (n=5). The proposed method was simple, rapid, little interference, a satisfactory recovery with high reproducibility, and could be successfully applied for the determination of fluoride in drinking water samples. |
