| Summary: | A review of the methods of test available for the measurement of lead in gasline has been made. Twelve methods are listed: seven cover the range of leadlevels found in commercial motor gasoline and five cover the trace lead range. The most precise method of measurement for motor gasoline, over a wide reange, is one based on cold extraction of lead with iodine monochloride reagent, coupled with a volumetric EDTA titration. For analysing typical Europeancommercial gasolines several instrumental methods have a comparable or better precision than this chemical procedure over the range from 0.1 to 0.5 g Pb/litre. Both chemical and instrumental methods are available for trace level determinations. |
