摘要
介绍了一种直接离子色谱法测定处理过的饮用水中存在氟化物、氯化物、硝酸盐、亚硝酸盐和溴化物的亚氯酸盐、氯酸盐和溴酸盐。采用AS19-HC分析柱(250 mm × 4 mm)， AG 19-HC保护柱(50 mm × 4 mm)， KOH 25 mmol/L为流动相进行分离。无机分析物以1ml /min的流速洗脱。设置柱温并保持在300℃。用抑制电导率检测器定量分析离子。
New ion-chromatography method for detection of chlorite, chlorate, and bromate in drinking water
A direct ion chromatographic method for the determination of chlorite, chlorate, and bromate in the presence of fluoride, chloride, nitrate, nitrite, and bromide in treated drinking waters was described. Separation of target analytes was achieved using an AS19-HC analytical column (250 mm x 4 mm), AG 19- HC guard column (50 mm x 4 mm), and KOH 25 mmol/L as mobile phase. Inorganic analytes were eluted using a flow rate of 1 mL/min. The column temperature was set up and maintained at 300C. The analyte ions
were quantified using a suppressed conductivity detector.
