Sažetak
In the paper are presented different spectroscopic methods for Pb determination, depending on concentration range in fuels. Pb mostly is added, in form alkillead compounds to improve antiknock effects in gasoline. In less part Pb is the component of petrol derivates, or it appears as a consequence of contamination in transport. Because of different Pb content in fuel, the applied analytic methods are also different. So for trace Pb Analyses, flameless atomic spectroscopy takes place, but for light and heavydistillates, flame atomic spectroscopy and lately X-ray spectroscopy applies. In this work the results are given, using all three methods of Pb determination and advantage of the choice method in identical concentration range. Precision of method (RSD) is better at high concentration levels and the value of 5 procent is shown, as long as at lower concentration show precision of 10 procent.
