    Abstract: 二異氰酸甲苯(Toluene diisocyanate, TDI)用途十分廣泛,主要作為聚氨基甲酸乙酯(polyurethane,PU)之製造,其產品的種類眾多,包括泡綿、塗料、樹脂、黏著劑、合成皮等。TDI在尿中的代謝物主要為二胺基甲苯(Toluene diamine, TDA),包含TDA原體、酯化與結合型式代謝物。本研究係開發一簡單且具高靈敏度的尿中TDA的分析方法,以高效率液相層析儀配合螢光偵測器測定尿中TDA,在樣品前處理方面,將尿液樣品以濃硫酸或氫氧化鈉進行水解後,再經C18及陽離子交換樹脂固相萃取管以去除基質干擾。研究結果顯示以固相萃取法可以有效的去除干擾,2,6-TDA與2,4-TDA回收率分別為75 %與82 %。
