摘要
研究用气相色谱测定海水及天然水中微量碘离子含量的快速分析方法,确定了最佳条件。水样经酸化后,用K2Cr2O将碘离子氧化威碘,再与丁酮反应约10min,生成碘代丁酮,用环己皖萃取后,用气相色谱仪的电子捕获检测器测定其含量。于1991年6月,用此法测定青岛胶州湾沿岸海水及某些河口水样,证明该方法简便、快速。
This paper presents an analytical method for determination of trace iodine an-ion in seawater and natural water by gas chromatography- After acidating the sam-ple water, the trace iodine anion is oxidated to free iodine which can react withbutyltone and produce iodobutanone. The iodobutanone can be determined by ECDdetector. This method is simple, rapid and has been used for determination of sur-face water and estuary water in Jiaozhou Bay (Qingdao) in 1991.
