摘要
介绍了用抑制型离子色谱法测定隔夜沸水中F-,Cl-,NO2-,H2PO4-,NO3-的含量的方法:流动相为4mmol/L Na2CO3与3mmol/L NaHCO3的混合溶液,流动相流速为1.5mL/min,进样量为0.5mL。5种阴离子在上述色谱条件下分离良好,检出限分别为0.005mg/L,0.01mg/L,0.04mg/L,0.08mg/L,0.06mg/L;用色谱软件绘制工作曲线,定量测定的线性相关系数均在0.995以上;样品回收率在99.6/～108/之间。
The paper introduces how to examine aniois content in the boiled water standed for night by ion chromatography with chemical suppression.
