| 摘 要： | 目的:建立大体积进样电导检测离子色谱法同时测定水中溴酸盐、亚氯酸盐、氯酸盐、二氯乙酸、三氯乙酸5种消毒副产物含量的方法。方法:采用Dionex IonPac AS-19高容量分析柱,进样体积为500μl,淋洗液自动发生装置在线产生KOH梯度洗脱,抑制型电导检测,柱温25℃～26℃,35 min内同时测定消毒副产物和水中常规阴离子。结果:测定的5种消毒副产物在5μg/L～2000μg/L浓度范围内呈良好线性关系,检出限低,测定相对标准偏差均小于3%,回收率在84%～117%之间。结论:该方法操作简便,实用性强,结果可靠。

| Abstract: | Objective:To establish a new conductivity detection ion chromatography determination method for contents of BrO-3,ClO-2,ClO-3,DCAA,TCAA in water by the large volume direct injection.Methods:In the suppressed conductivity detection,Dionex IonPac AS19 column was used as separation column,sample injection volume at 500 μl,with KOH gradient elution generated by on-line eluent generator.Column temperature was 25℃～26℃.DBPs and conventional anion in water were detected in 35 min at the same time.Results:The DBPs content showed good linearity within the concentration range of 5 μg/L～2000 μg/L.Limit of determination was low.Relative standard deviations(RSD) was less than 3%,recoveries were between 84%～117%.Conclusion:The method is simple,practical and reliable. |
