Chemical Analysis of the Dyes Used in Navy Green and Yellow Colored Smokes .
Abstract
The organic dyes used in Navy green and yellow colored smokes can contain up to 23% unknown/undefined impurities. These impurities may be hazardous by themselves, or may form hazardous products after combustion. In some cases, they may also affect the burning rate and burning efficiency of the colored smokes. This paper provides the results of a complete qualitative analysis on the aforementioned green and yellow dyes, including the side products formed in the manufacturing process. The investigative techniques included gas chromatography (GC), gas chromatography/mass spectroscopy (GC/MS), nuclear magnetic resonance spectroscopy (NMR), liquid chromatography (LC), thin layer chromatography (TLC), atomic absorption spectroscopy (AA) and energy dispersing x-ray analysis (EDXA). Keywords: Pollution abatement studies, and Thermal degradation.
