DEVELOPMENT OF A PROCEDURE FOR DETERMINING TRACE QUANTITIES OF ZINC IN AIRCRAFT AND AUTOMOTIVE ENGINE FUELS.

Abstract

A dithizone spectrophotometric procedure was developed for the determination of trace amounts of zinc in aviation and automotive engine fuel. The analysis of zinc in fuel containing alkyl lead antiknock involves a modification requiring the electrolytic removal of lead and the complexing of residual traces of the same element with sodium di-ethyl di-thiocarbamate. It was found that with fuels not requiring alkyl lead antiknock the developed method gave an average error from -0.2 to + 0.3 PPM in the range of 1 to 15 PPM zinc whereas the modification for use with fuels requiring alkyl lead antiknock gave a positive error amounting to 1.5 to 3.5 PPM depending on zinc concentration.
