Colorimetric Oil Analysis for Titanium.

Abstract

The goal of this research contract was to develop a rapid flight-line method compatible with the Colorimetric Iron Kit for assessing the titanium content in used jet engine lubricating oil. A colorimetric method capable of analyzing for up to 20 ppm titanium was developed for this purpose. The method extracts the titanium from the oil into an aqueous phase where it is complexed with TIRON to form a yellow color indicative of the titanium concentration. The titanium concentration can be quantitated by measuring the yellow aqueous layer with a spectrophotometer or colorimeter at 400 micrometers. (Author)
