    1. Scope

    This method is for determining the total chloride content of fresh, regenerated, and spent alumina supported catalysts by wavelength dispersive x-ray fluorescence (WD-XRF) spectroscopy. The range of quantitation is from 0.01 to 3 mass-% and applies to samples containing less than 10 mass-% water and other volatiles as determined by loss on ignition (LOI) measurement at 900 C. 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.
