摘要
本文探讨了离子色谱法测定混凝土外加剂中无机氯离子以及样品的前处理方法。实验中采用SEP-RP预处理柱,利用此富集柱可以有效的去除混凝土外加剂中的有机化合物,提高色谱柱效。
This paper introduced a new method of using ion chromatograph (IC) to test chloridion in the concrete additives and also pointed out that organics in concrete additives can be effectively removed by SEP-RP columns but inorganic chloridion is not absorbed.Pre-column can greatly increase IC efficiency and improve separation.
