摘要
应用GC MS联机检测技术对我国大陆和香港共 1 1个城市污泥中 4种醚类和 4种卤代烃类化合物进行分析 .结果表明 ,醚类化合物的总含量在 0— 7 743mg kg之间 ,以双 (2 氯异丙基 )醚为主 ,主要分布在兰州污泥和广州污泥中 ;卤代烃类化合物的总含量在 0 0 0 7— 3 2 37mg kg之间 ,以六氯环戊二烯为主 ,主要分布在兰州污泥、佛山污泥和沙田 (香港 )污泥中 .污泥中醚类和卤代烃类化合物的种类及其含量与污水来源、污水处理方式、污泥类型。
Four ethers and four halogenated hydrocarbon compounds classified as US EPA priority pollutants in eleven municipal sludges from selected cities of China were determined by GC/MS. The total contents of ethers in various sludges ranged 0—7 743?mg/kg. Bis(2 chloroisopropyl) ether was the most dominant one which distributed chiefly in Lanzhou sludge and Guangzhou sludge. The total contents of halogenated hydrocarbons ranged 0 007—3 327?mg/kg. Hexachlorocyclopentadiene was the most dominant one which distributed mainly in Lanzhou sludge, Foshan sludge and Shatian (HongKong) sludge. The type and concentration of ethers and halogenated hydrocarbons in different municipal sludges were related to the source of wastewater, wastewater treating method, sludge type, physical chemical property of ethers and halogenated hydrocarbons themselves, and so on.
