大气环境中二硫化碳分析方法的选择研究

The Research for the Method of Determination of CS 2 in Atmospheric Environment.

应用气相色谱（ＧＣ）Ｎｉ６３电子捕获检测器（ＥＣＤ），在６２０１红色担体为基体，涂１０％ＯＶ－１０１固定液的玻璃柱上，以甲苯作吸收液，对大气环境中微量二硫化碳能够进行定量检测，其最低检出浓度可达６×１０－６ｍｇ／ｍｌ（进液体样品１μｌ）；方法精密度为３．４％，ＳＯ２、Ｈ２Ｓ气体物质不干扰测定。经现场实际环境样品测试，此方法能够适用于大气环境中微量ＣＳ２的分析工作，为大气环境监测微量ＣＳ２的分析建立了一个比较合适的方法。

A method of applying Ni 63 Electron Capture Detector (ECD) of Gas Chromatography (GC) to quantitative determination of trace CS 2 in atmospheric environment is reported.The detective limit is 6×10 -6 mg/ml (inject liquid sample 1μl),the precision of the method is 3 4%,the interference of gaseous substance such as SO 2、H 2S、etc,doesn't exist.Through the determination of environmental samples,the method is suitable for analysis of trace CS 2 in atmospheric environment.
