离子色谱法同时分析水样中多种阴离子成份
Determination of inorganic anions in water samples simultaneously by ion chromatography
摘要
Abstract
In this paper, the contents of F- , C1- , Br- , NO3- , pO34- and SOl- in water samples were deter- mined by ion chromatography simultaneously. The separation of six anions was achieved on a high capacity A- SSUP-5 column with NazCO3-NaHCO3 as mobile phase. The detection was performed by a suppressed conduc- tivity detector, with a 20 p~L loop for sample injection. The composition and flow velocity of mobile phase were optimized respectively. Under certain experimental conditions, there exists linear correlation between the con- tents of various anions and peak areas ( R 〉 0. 9992) , with a detection limit in the range from 0.05 ~ 0.23 mg/L and relative standard deviation (RSD) less than 3.6%. The recovery results for drinking water resource and tapping water samples were between 88.2% - 105.7%. The proposed method is proved to be convenient, quick, accurate and excellent application in water quality monitoring requirement.关键词
