| 摘 要： | 目的建立同时测定饮水中的氟化物、氯化物、硝酸盐氮和硫酸盐的离子色谱测定法。方法依据生活饮用水卫生规范(GB/T 5750-2006)对样品进行测定。3.6 mmol/L的碳酸钠溶液作淋洗液,使用SI-524E色谱柱和SI-90G保护柱进行离子色谱法测定。结果最低检出限分别为F-0.02 mg/L、Cl-0.01 mg/L、NO3-0.006 mg/L、SO42-0.50 mg/L,回收率在98%～103%之间,相关系数均大于0.999。结论该方法灵敏度高,回收率好,操作简便,工作强度低,适合于水质分析中F-、Cl-、NO3-、SO42-这4种阴离子的含量测定。

| Abstract: | [Objective]To establish a method for simultaneous determination of fluoride,chloride,nitrate and sulfate in drinking water by ion chromatography. [Methods]]The determination was based on theHygienic Standard for Drinking Water(GB/T 5750-2006).Samples was separated in SI-524E column and SI-90G protection column with 3.6 mmol/L sodium carbonate(Na2CO3) as eluent. [Results]The detection Limits were F-0.02 mg/L,Cl- 0.01 mg/L,NO3-0.006 mg/L and SO42-0.50 mg/L.Recoveries ranged from 98% to 103%,and correlation co... |
