摘要
采用硫化学发光检测-宽口径石英毛细管柱气相色谱法,建立了废气中羰基硫、硫化氢、二硫化碳、甲硫醇、乙硫醇、甲硫醚、乙硫醚、丙硫醇、异丙硫醇、噻吩及二甲二硫等11种挥发性硫化物的分析方法。硫化学发光检测器的灵敏度、选择性及线性范围均优于传统的火焰光度检测器。进样体积为0.2 ml时,硫化物的检出限为0.03～0.1 mg/m3。实际样品5次测定的相对标准偏差小于5.1%,加标回收率为83.7%～108.8%。测定了某炼油厂酸性水罐尾气、污油罐尾气及瓦斯气中挥发性硫化物,为其恶臭控制与治理提供检测手段和基础数据。
Sulfur chemiluminescence detector-vast capillary gas chromatography has been conducted on the analysis of volatile sulfur compounds in waste gases.The recoveries of hydrogen sulfide,carbon disulfide,methyl mercaptan,ethyl mercaptan,carbon disulfide,dimethyl sulphide,diethyl sulphide,n-propyl merrcaptan,i-propyl merrcaptan,thiophene and dimethyl disulfide were from 83.7% to 108.8%,the relative standard deviations were less than 5.1%.When inject volumn was 0.2 ml,the minimum detection levels of the above-mentioned volatile sulfur compounds varied between 0.03 mg/m3 and 0.1 mg/m3.Volatile sulfur compounds in waste gases from sour water tanks and oil tanks in an refinery and Gas were analyzed.
