Determination of tetraethyllead in gasolines by high performance liquid chromatography
A high-performance liquid chromatographic (HPLC) method for the determination of tetraethyllead (TEL) in gasolines has been developed. The method is based on the separation of TEL from other uv absorbing material on silica gel and quantification of the uv detector response. TEL concentrations corresponding to as little as 0.03 ..mu..g Pb in the sample (corresponding to 0.01 g Pb/imp. gal) could be determined quantitatively. The response of other alkalleads (tetramethyllead (TML) and mixed alkylleads (TML/TEL)) differs appreciably from that of TEL, precluding the use of this method for unknown samples. However, the analysis can be done in 5 min using commercially available equipment and can be used in all cases where the type of alkyllead present in the gasoline is known.
