Abstract
A sensitive method for the determination of tert-butylphenols in environmental samples was developed using GC/MS. Thetert-butylphenols in water were adsorbed on solid phase extraction (ENVI-18) and eluted with hexane. The eluate was dehydrated, and concentrated with nitrogen-gas.
The test-butylphenols in sediment were extracted with acetone, and in fishes were extracted with acetonitrile. Then thetest-butylphenols in acetone and acetonitrile were extracted with hexane. The extract was dehydrated, concentrated with nitrogen-gas and cleaned up by using LC-Florisil for GC/MS determination. Overall recovery rates were 51-87 % for water, 68-87 % for sediments, and 111-125 % for fishes, respectively.
The detection limits were 0.0067 0.011μg/l in water, 0.16-0.66μg/kg in sediment and 0.35-0.79 μg/kg in fishes.
