Method detection limit determination and application of a convenient headspace analysis method for methyl tert-butyl ether in water.

摘要: Methyl tert-butyl ether (MTBE) is a common groundwater contaminant, introduced to the environment by leaking petroleum storage tanks, urban runoff, and motorized watercraft. In this study. simplified (static) headspace analysis method was adapted for determination of MTBE in water samples soil extracts. The MDL calculated be 2.0 microg L(-1) EPA single-concentration design method(1) 1.2 calibration developed Hubaux Vos (Hubaux, A.; Vos, G. Anal. Chem. 1970,42, 849-855). with favored because it considers both true positive false positive. static applied tap sample monitoring well from gasoline service station, river sample, aqueous extracts excavated during removal underground tank (LUST). examined study had MTTBE concentrations ranging 6 19 L(-1). Aqueous taken LUST site 8 MTBE.
