离子色谱法测定饮用水中的7种阴离子

Determination of Seven Anions in Life Drinking Water by Ion Chromatography

采用离子色谱法测定水中F^-、Cl^-、NO_2^-、Br^-、NO_3^-、PO_4^(3-)、SO_4^(2-)离子,具有选择性好、灵敏度高和分析速度快等特点。该方法的最低检测浓度为0.01 mg/L,回收率为99.1%~102.0%。

Determing the F-、Cl-、NO_2-、Br-、NO_3-、PO_4（3-）and SO_4（2-）in water by ion chromatography has the advantages of good selectivity,high sensitivity and fast analysis speed.The minimum detection concentration of this method is 0.01 mg/L,and the recovery rate is 99.1%102.0%.
