本研究主要以SPME/GC/FID的方式,來進行水中鄰苯二甲酸酯類的採樣分析。
SPME/GC/FID採樣分析技術的建立,首先參考相關文獻選定PDMS/DVB材質的纖維為固定靜相吸附纖維,接著完成固相微萃取技術最佳化測試,經由最佳化過程中發現DMP、DEP、DnBP、BBP與DEHP的檢測皆可以達到ppb級的濃度,檢量線測試實驗中R2均在0.995以上,唯獨目標污染物DnOP不易被偵測到。而研究過程中發現PDMS/DVB吸附纖維對於DnBP、BBP此兩種目標污染物具有較佳的萃取能力。
實測樣品結果顯示,自來水、蒸餾水、去離子水中受到鄰苯二甲酸酯類的污染較小;在咖啡壺煮過的水樣中,發現DnBP為主要污染物,鄰苯二甲酸酯類化合物可能是在加熱過程中,由咖啡壺釋放至水樣中,奶嘴的主要材質為PVC,將奶嘴直接放在水中震盪,結果顯示水樣中含有不少的DEP污染物;生理食鹽水的包裝材質為HDPE,研究結果發現,生理食鹽水中含有微量的DEP、DnBP。
