采用自制气体富集装置，将水中苯、甲苯、二甲苯等芳香烃富集后结合吸附热解吸浓缩法导入气相色谱（ＧＣ）仪进行了分析，以４倍噪音为检测限，检测浓度为１０．５～１６．９μｇ／Ｌ，比富集法提高了２０～５３倍．并探讨了各种操作条件对色谱灵敏度的影响，采用标准加入法，初步测定武汉长江水、东湖水、南湖水和自来水中芳香烃的含量． Adopting self-made gas enrichment device, the aromatic hydrocarbons in water, such as benzene, toluene and xylene, were enriched and then analyzed by gas chromatography (GC) with adsorption desorption and concentration method. The detection limit was 4 times of noise. 10.5 ~ 16.9μg / L, 20 ~ 53 times higher than enrichment method. The effects of various operating conditions on the chromatographic sensitivity were also discussed. The standard addition method was used to determine the content of aromatics in the Yangtze River, East Lake, South Lake and tap water in Wuhan.
