DETERMINATION OF INDIVIDUAL AND TOTAL LEAD ALKYLS IN GASOLINE BY A SIMPLE RAPID GAS CHROMATOGRAPHY/ATOMIC ABSORPTION SPECTROMETRY TECHNIQUE

A procedure is described, which uses a gas chromatographic attachment to an atomic absorption spectrometer, for the analysis of individual and total lead alkyls in leaded or unleaded gasoline. The attachment, which operates isothermally, does not use a complete chromatograph, and can be made from inexpensive components. The method is faster than most comparable techniques and has a through-put time of about five minutes per sample; no sample preparation is required and the precision of the method is comparable with the standard ASTM/1P X-Ray fluorescence technique. The detection limit is around 0.2 ppm lead for each alkyl and the method is suitable for trace lead levels in unleaded gasoline. With some modifications, this limit could probably be lowered to levels sufficiently low for pollution monitoring applications.
