被動式采樣器在大區域大氣VOC監測中的應用 APPLICATION OF PASSIVE SAMPLER IN WIDE RANGE MEASUREMENT OF AIR VOC

【摘要】 應用VOC被動式采樣器監測了地中海東部塞浦路斯島大氣中揮發性有機化合物(volatile organic compounds,VOC)的濃度。通過島上設置的80個VOC采樣點對苯,甲苯,對、鄰、間二甲苯(Benzene、Toluene、o-xylene、m,p-xylene,BTX)數次采樣及分析結果表明,其被動采樣器中BTX回收率>95%,BTX平行實驗的相對標準偏差<6.28%,采樣和分析方法準確。得到的污染物分布圖較準確地反映了塞浦路斯島實際污染情況。

【Abstract】 The distribution of the air VOC(volatile organic compounds) in Cyprus Island located in east Mediterranean Sea using the VOC passive sampler was measured.80 sample points were pertinently set up to measure benzene,toluene,o-xylene,m-xylene,and p-xylene.Analytical results show that:the recovery of VOC was beyond 95%, and the relative standard deviation (RSD) of BTX parallel experiments was below 6.28%.Sampling and analytical method is accurate.The real pollution instance of Cyprus Island was refl... 更多
