离子色谱法在测定宜昌市地表水水质中的应用

Application of Ion Chromatography in Determining Surface Water Quality in Yichang City

地表水水质监测常规指标中的无机阴离子主要包括氟离子、氯离子、硝酸根离子、硫酸根离子,采用瑞士万通离子色谱仪对宜昌市地表水中的氟离子、氯离子、硝酸根离子、硫酸根离子进行同时测定,实验结果表明:用离子色谱法测定地表水中氟离子、氯离子、硝酸根离子、硫酸根离子具有较好的精密度和准确度,同时检出限等指标符合《水质无机阴离子的测定离子色谱法》(HJ 84-2016)的标准要求。

The inorganic anions in the conventional indicators of surface water quality monitoring mainly include fluoride ion,chloride ion,nitrate ion,and sulfate ion.The fluorine ion,chloride ion,nitrate ion and sulfate ion in the surface water of Yichang city were measured simultaneously by Vantone ion chromatograph.The experimental results show that the determination of fluoride ions,chloride ions,nitrate ions and sulfate ions in surface water by ion chromatography has good precision and accuracy,and the detection limit and other indicators meet the standard requirements of"Ion chromatography for the Determination of Inorganic anions in Water Quality"(HJ 84-2016).
