环境监测实验室水中氟化物检测能力及检测方法比对
|
摘要
本文通过深入了解当前环境检测实验室水中氟化物的检测能力水平,分析水中氟化物的检测过程,总结出最有效的水中氟化物检测方法。选取四川省93家实验室进行水中氟化物检测能力的评定,并将其检测方法进行比对,实验室通过离子色谱法或电极法进行检测,以稳健四分位的统计方法来对检测结果进行评定比对。最后发现参加本次研究的93家实验室对于水中氟化物的检测能力水平从总体方面来说较为良好,但是有个别的氟化物检测能力以及结果与一般水平有较大的差别,引起偏差的影响因素有待进一步考证和探讨。
This paper analyzes the detection process of fluoride in water by analyzing the detection ability of fluoride in water in the current environmental testing laboratory, and summarizes the most effective method for detecting fluoride in water. 93 laboratories in Sichuan Province were selected to evaluate the ability of fluoride detection in water, and their detection methods were compared. The laboratory was tested by ion chromatography or electrode method, and the results were tested by robust quartile statistical method. Evaluate the comparison. Finally, it was found that the 93 laboratories participating in the study had a good overall level of detection of fluoride in water, but there were individual fluoride detection capabilities and results that were significantly different from the general level, causing bias effects. Factors need to be further researched and discussed.
