溴系阻燃劑常廣泛地被應用在我們生活週遭的許多產品當中,像是家電用品、電子電機產品、建築材料以及紡織品...等等。其中,四溴雙酚A為被使用最多的溴系阻燃劑之ㄧ。本研究首先利用X光螢光分析儀對溴進行定性的檢測;再來針對水浴式超音波震盪萃取、探針式超音波震盪萃取、索氏萃取三種不同之前處理方式進行塑膠材質中的四溴雙酚A含量萃取回收率的比較,並以氣相層析質譜儀進行定性與定量之分析。 研究結果顯示,三種不同之萃取方式在最佳化條件下,皆有相近且良好的回收率。以商業實驗室而言,不論在時間上、成本上、效率上、樣品處理量上皆要考慮到最適合的條件,而水浴式超音波震盪萃取實為商業化考量下之最佳條件;探針式超音波萃取則適用在樣品處理量少且含待測物四溴雙酚A時,進行再確認之動作;索式萃取方式對商業實驗室來說,則是不敷成本。
Brominated flame retardants are widely applied in our daily necessities such as household appliances, electronic product, building material and textiles...etc. Tetrabromobisphenol A is one of the most important brominated flame retardants used in commerce. In this study, we used X-Ray Fluorescence to screen out the sample containing brominated compounds. In this study, three different extraction methods such as water bath ultrasonic vibration, probe ultrasonic vibration and soxhlet extraction method are compared. Gas chromatography coupled with mass spectrometry is employed for qualitative and quantitative analysis of brominated compound. A commercial laboratory has to design the optimum operation method based on operation time, cost, efficiency and number of samples to reduce their operation cost. The best extraction method for sample preparation is water bath-type ultrasonic vibration extraction. Probe ultrasonic vibration extraction is the best choice for double-checked action. Soxhlet extraction is not adaptable in a commercial laboratory, since it takes a lot of time and can’t treat a lot of samples in one pretreatment.
