Abstract
Rapid analysis of cosmetic clay minerals such as Talc, Kaolin etc. was studied by fluorescent X-ray spectrometry. It was said to effect much the differences of sample's composition and partical size in this study. In order to reduce these effects, a fusing technique was introduced as a pretreatment.
Several standard mixtures were made similar to the composition of Talc and Kaolin, the calibration curves of every composition were determined. They were found linear. Using these curves, practical samples ware analyzed. The analytical results of the present method coincided well with those of chemical wet analysis.
The present method was found to be of great advantage in time and procedure to the chemical wet analysis.
