摘要
通过萃取的方法对样品进行前处理,离子色谱法对聚酰亚胺原材料6FAP中的氯离子进行定量分析。方法检出限4.5μg·L^(-1),相对标准偏差(RSD)小于1%,样品氯离子加标回收率为95%~105%。结果表明,本方法具有可行性,可为聚酰亚胺的原料中的氯离子分析提供一定参考。
The sample was pre-treated by extraction method,and the chloride ion in polyimide raw material 6FAP was quantified by ion chromatography.The limit of detection was 4.5μg·L^(-1),the relative standard deviation(RSD)was less than 1%,the recovery of chloride ion was 95%~105%.The results showed that this method was feasible,and it could provide a reference for the analysis of chloride ion in polyimide raw materials.
