| 摘 要： | 利用MIC型离子色谱仪，对饮用水中F^-、Cl^-、NO2^-、NO3^-、P04^3-和SO4^2-阴离子进行检测。采用Supp5-4．0mm＊150mm离子色谱柱，3．2mol/L碳酸钠和1．0mol／L碳酸氢钠淋洗液，抑制型电导检测。结果表明，利用这个离子色谱的最佳条件可以对饮用水中的8种阴离子同时准确快速地定性定量检测。F^-、HCOO^-、Cl^-、NO2^-、Br^-、NO3^-、PO4^3-和SO4^2-的相对标准偏差为：1．588％-3．270％，检出限为：0．012mg／L-5．076mg／L，回收率为：94．0％～105．2％。实验结果发现有水样中的F含量超出国家标准。

| Abstract: | 8 kinds of drinking water were measured with the MIC ion chromatography. The chromatography conditions were used as follows： Supp 5-4.0 mm＊150 mm anion column, effluent of 3.2 mol/L sodium carbonate and 1.0 mol/L sodium bicarbonate and suppressed conductivity detection. The contents of F, HCOO, Cl, NO2, Br, NO3, PO43- and SO42 in drinking water were determined by ion chromatography （IC） . This method can determine the contents of eight kind of anions aqueous sample quickly and accurately. The relative standard deviations of the above eight kind of anions were 1.588%-3.270%, and the detection limits were 0.012 mg/L-5.076 mg/L while the percent recovery were 94.0%-105.2%. The results showed that the F- content of one mineral water sample exceeded the limit of the national standards. |
