本文介绍在盐酸酸性条件下,将海水及沉积物中微量三丁基锡化合物转变成氯化三丁基锡(TBTC),以正己烷萃取,然后用配有电子捕获检测器的气相色谱仪进行分析。仪器岛津GC-7 APE(检测器:~(63)Ni 10mCi)。有机汞分析柱,内填充Thermon-HG。积分仪:连接岛津C-R l A型色谱组件,用其测定保留时间,峰高,峰面积。索氏提取器。本法气相色谱条件见表。试剂 TBTC标准溶液:吸取1 ml TBTC(纯度:98%,比重1.20)溶于100 ml正己烷溶液中,将此液作为原液,临用时根据所需
This article describes the conversion of traces of tributyltin in sea water and sediments to tributyltin chloride (TBTC) in hydrochloric acid under acidic conditions, followed by extraction with n-hexane, followed by gas chromatography with an electron capture detector. Instrument Shimadzu GC-7 APE (detector: ~ (63) Ni 10mCi). Organic mercury analytical column, filled Thermon-HG. Integrator: Connect Shimadzu C-R l A-type chromatographic components, with its determination of retention time, peak height, peak area. Soxhlet extractor. Gas chromatography conditions in this table. Reagents TBTC standard solution: Pipette 1 ml of TBTC (purity: 98%, specific gravity 1.20) was dissolved in 100 ml of n-hexane solution, this solution as a stock solution, when used as needed
