Full Description

This method is for determining the total chloride content of fresh, regenerated, and spent alumina supported catalysts by wavelength dispersive x-ray fluorescence (XRF) spectroscopy. The range of quantitation is from 0.01 to 3 mass-% and applies to samples containing less than 10 mass-% water. The upper concentration limit of the method can be extended if appropriate standard and reference materials can be obtained. See NOTES for matrix-effect and other interferences.
