摘要
本文建立了饮用水中亚氯酸盐、氯酸盐和溴酸盐的离子色谱检测方法,并对方法中的线性、精密度、加标回收率等参数进行了考察。实验结果表明,亚氯酸盐、氯酸盐和溴酸盐在4.00~60.0μg·L^(-1)浓度范围内呈良好的线性关系,相对标准偏差均小于2%(n=6),加标回收率在92.0%~104.0%之间,符合样品分析质量要求。本方法操作简便,实用性强,灵敏度高,测定结果准确可靠,适用于水中亚氯酸盐、氯酸盐和溴酸盐残留的监测。
In this paper,the detection methods of chlorite,chlorate and bromate in drinking water by ion chromatography were established,and the parameters of linearity,precision and recovery rate were investigated.The experimental results showed that the chlorite,chlorate and bromate have a good linear relationship in the concentration range of 4.00~60.0μg·L^(-1),the relative standard deviation is less than 2%(n=6),and the recovery of standard addition is between 92.0%~104.0%,which meets the quality requirements of sample analysis.The method is simple,practical,sensitive,accurate and reliable.It is suitable for the monitoring of chlorite,chlorate and bromate residues in water.
