摘要
用新型测定卤素的方法：石墨炉原子化元素特种检测器检测法，研究了氯元素在该仪器上的响应行为；测定出该方法对氯元素的检出限为５ｎｇ，线性范围为１０ｎｇ～１．５μｇ，平均相对标准偏差为２．６５％，用该法对实际水样品的测定结果与离子色谱法测定结果相吻合。研究结果亦表明，这种新型分析方法具有简单、快速、对卤素选择性好、可测无机氯和有机氯的特点。
The element specific detector(ESD)is connected to a graphite furnace HGA-500。By means of this new analytical technique,the determination of chloride compound in differentsamples has been tried.Samples are prepared using Li-form exchange resin, then analyseddirectly. The detection limit is 5 ng and the relative standard deviation(RSD)is 2.65%. Thedetermination of real samples shows that the new analysis method is simple,reliabe and suitablefor the determination of chloride in natural water.
