Abstract
A GC/MS method for determination of tetrabromobisphenol A (TBBP-A) in environmental samples was developed. The target compound in water sample, adjusted to pH 3.5 with hydrochloric acid, was extracted with two styrene-divinylbenzene copolymer (Sep-Pak Plus PS-2) cartridges in a series and was eluted with ethyl acetate. After derivatization with N, O-bis (trimethylsilyl) trifluoroacetamide (BSTFA), the resulting trimethylsilyl derivative was determined by GC/MS. TBBP-A in sediment or fish sample was extracted with methanol, partitioned with hexane, and re-extracted with dichloromethane. TBBP-A in the extract was derivatized to ethyl derivative using diethyl sulfate. The derivative was extracted with hexane and was cleaned up by using a Florisil cartridge for GC/MS determination. Overall recoveries from water, sediment and fish were 89 %-101 %, 91 % and 82 %, respectively. The minimum detection limits were 0.055 μg/l in water, 5.5 μg/kg in sediment and 20 μg/kg in fish.
