| 摘 要： | 对离子色谱法测定氯含量常用的IonPac AS14A保护柱和新型IonPac AS23分析柱进行对比实验,选择了IonPac AS23柱作为分析柱。解决了碳酸盐对氯离子测定的干扰,优化色谱条件,同时分析牛皮纸样袋中海底沉积物中的氯含量测定结果偏低的原因,拟定了准确测定牛皮纸样袋中海底沉积物中氯含量的方法。通过测定国家一级标准物质中氯含量,结果与标准值相符,其相对标准偏差≤2.66%。

| Abstract: | In order to eliminate the interference from carbonate on the determination of chlorine, a new IonPac AS23 column was selected in determination of chlorine in marine sediments through the comparative trial between commonly used IonPac 14 column and IonPac AS 23 column. The causes led to lower concentration results of chlorine in marine sediments were discussed when kraft bag was used for sample storage. Under the optimized determination condition, the method has been applied to the determination of chlorine in national standard marine sediments. The results are in agreement with the certified values with precision of less than 2.66%RSD. |
