摘要
目的:比较离子选择电极法与离子色谱法在生活饮用水氟化物检测中的效果。方法:于2020年6月-2021年6月采集某市区集中式饮用水源地的35份水样,对所有水样分别施以离子选择电极法与离子色谱法检测。比较两种不同的检测方法的氟化物含量检测结果与检测人员工作时间。结果:两种不同检测方式水源样本内的氟化物浓度均在1.0 mg/L的饮用水标准之下,其中离子色谱法水源样本内的氟化物平均浓度为(0.19±0.02)mg/L,离子选择电极法水源样本内的氟化物平均浓度为(0.18±0.03)mg/L,两种检测方式的氟化物浓度检测结果比较,差异无统计学意义(P>0.05);两者的平均加标率相比,差异无统计学意义(t=1.915,P=0.060);离子色谱法检测人员工作时间为(2.00±0.50)h,短于离子选择电极法的(2.85±0.59)h,差异有统计学意义(P<0.05)。结论:离子选择电极法与离子色谱法在生活饮用水氟化物检测中均具备较为优良的检测效能,但离子色谱法检测水氟浓度中的检测人员花费的时间更短,值得临床推广应用。
Objective:To compare the effects of ion selective electrode method and ion chromatography in the detection of fluoride in drinking water.Method:35 water samples from a centralized drinking water source in an urban area were collected from June 2020 to June 2021,all water samples were detected by ion selective electrode method and ion chromatography respectively.The fluoride content detection results of the two different detection methods and the working hours of the inspectors were compared.Result:The fluoride concentration in the water source samples of the two different detection methods was below the drinking water standard of 1.0 mg/L,and the average concentration of fluoride in the water source samples by ion chromatography was(0.19±0.02)mg/L,the average concentration of fluoride in the water source sample by ion selective electrode method is(0.18±0.03)mg/L,and the difference between the two detection methods of fluoride concentration detection results is not statistically significant(P>0.05);there was no significant difference in the average standard addition rate between the two(t=1.915,P=0.060);the working time of the detection personnel of ion chromatography was(2.00±0.50)h,which was shorter than(2.85±0.59)h of ion selective electrode method,the difference was statistically significant(P<0.05).Conclusion:Both ion-selective electrode method and ion chromatography have better detection efficiency in the detection of fluoride in drinking water,but the time spent by the detection personnel in the detection of fluoride concentration in water is shorter by ion chromatography,which is worthy of clinical application.
