Abstract

A new method for determination of residual flotation oils on beneficiated kaolin clays has been developed. The method, which yields qualitative information, is based on fluorescence measurements employing a spatially resolved, polychromatic illumination source for excitation, and a two-dimensional detection scheme using a silicon-intensified, video imaging device. The method was used to identify residual oils on a beneficiated, Washington County, Georgia, crude clay. The results were compared to a similar qualitative analysis performed via capillary column gas chromatography using a flame ionization detector. The video fluorometry was the preferred method of analysis. 7 refs.
