Abstract:

Usually, for the determination of trace concentration of lead in gasoline, a routine sample pre-treatment procedure (such as iodine monochloride method or boiled hydrochloric extraction method) is coupled with a spectrometric detector, because tetraethyl lead and tetramethyl lead were added in gasoline as a antiknock component. These methods involved, however, are often complex, time-consuming, labor-intensive and,hence, susceptible to errors and pollution. Use of microwave energy enhance extraction of organic compounds from solid matrices was reported, but, enhance extraction of organic compounds from organic matrices (in especial from the gasoline), then turning the extraction substance into an inorganic compound was not reported.
