衍生气相色谱法测定水中2,4,6-三氯酚、五氯酚

Determination of 2,4,6-Trichlorophenol and Pentachlorophenol in Water by Derivative Gas Chromatography

环境中氯酚类化合物主要来源于石油化工、塑料制造、颜料合成、制药、造纸等工业的废水排放,容易造成环境污染。氯酚类化合物含量是表征环境中有机物污染程度的重要指标。如果环境中存在较多氯酚类化合物,要对其进行降解处理,否则会影响环境安全。若废水不经处理便通过明渠进行灌溉,氯酚类化合物便会挥发进入大气或渗入地下和河道。

Chlorophenols in the environment mainly come from the wastewater discharge of petrochemical industry,plastic manufacturing,pigment synthesis,pharmacy,paper making and other industries,which is easy to cause environmental pollution.Chlorophenols content is an important indicator to characterize the degree of organic pollution in the environment.If there are more chlorophenols in the environment,they should be degraded,otherwise the environmental safety will be affected.If the wastewater is irrigated through open channels without treatment,chlorophenols will volatilize into the atmosphere or infiltrate into the ground and rivers.
