| 摘 要： | 采用静态顶空气相色谱法,ββ-’氧二丙腈填充柱,火焰光度检测器(FPD),研究了气液体积比、平衡温度、平衡时间、ρ(NaCl)等因素对废水中甲硫醚测定的影响,建立了废水中甲硫醚测定的新方法,取得了0.02 mg/L的检出限、97.6%~103.4%的回收率和0.7%~2.0%的相对标准偏差。该方法简单,快速,准确。

| Abstract: | Based on the method of static headspace-GC with β-β'oxydipropionitrile packed column and flame photometric detector(FPD),factors influencing the determination such as equilibrium temperature,equilibrium time,gas and liquid phase ratio,concentration of salt in water were discussed.A new method of determination of the dimethyl sulfide concentration in wastewater is established.And the detection limit is 0.02 mg/L.The recovery of dimethyl sulfide falls within the range of(97.6)%～103.4%,and corresponding RSD within 0.7%~2.0%.The method is simple,direct and accurate. |
