摘要
研究了一次进样同时测定饮用水中F-,ClO2-,BrO3-,Cl-,NO2-,Br-,CLO3-,NO3-,SO42-,H2PO4- 10种阴离子的离子色谱方法,选择出了最佳的色谱条件,各种离子峰能够完全分离。对方法的检出限,标准曲线测定范围,精密度,准确度和干扰物质的影响作了较详尽的试验,得到了满意的结果。离子色谱方法灵敏度高,选择性好,简便快速,适用于饮用水中不同浓度上述10种阴离子的分析。
A method to determine concentration of 10 anions in drinking water including F , ClO2-, BrO3-, cl-, NO2-, Br-, ClO3-, NO3- , SO42-, H2PO4- by ion chromatography with only one injection at the same time has been established. The best condition of chromatography is selected. Kinds of ion peaks are separated. A great deal of experiments have been done as to precision, accuracy, affects of interference substances in the established methods, calibration curve and the range of determination. The results prove that this analytic method has high sensitivity, selectivity and easy to operate, and it is fit for the determination of the above 10 kinds of anions in drinking water.
