Abstract

ASC whetlerite is a high surface area (650 m**2/g) charcoal that has been impregnated with copper, chromium, and silver salts. The objective of the current investigation was to determine a nondestructive method by which both the loss in ASC whetlerite chemical activity could be quantified and the deactivation process elucidated. Small pulses of hydrogen could be used to determine the magnitude of the Cr** plus **6/Cr** plus **3 ratio on ASC whetlerite. Since a drop in this ratio is associated with increased deactivation, hydrogen can be used to probe the surface of whetlerite to determine its degree of chemical deactivation.
