Determination of aluminum soaps in pitch deposits by gas chromatography
Source abstract
Abstract
Aluminum soaps can be determined by formation of aluminum-acetylacetonate chelates that are volatile enough to be analyzed by gas chromatography. Application of the technique to pitch deposits containing aluminum soaps entails acid hydrolysis to break down the aluminum soaps, chelation of the aluminum with acetylacetonate at pH >6, and analysis of the aluminum chelates by gas chromatography. The technique offers results that are comparable to those obtained by a traditional, much longer method that requires acid digestion of aluminum soaps and analysis of aluminum content by inductively coupled plasma spectroscopy.
