| Abstract: | Abstract A nondestructive analysis for chemical reactivity of commercial whetlerite (activated charcoal impregnated with copper, chromium and silver) is described. It is based on monitoring the disappearance of carbon monoxide in mixtures with air from known flows passing through the charcoal in a flow-through mode. Correlation of CO oxidation was found with measurements of cyanogen chloride retention using the same samples. the disappearance of carbon monoxide was also followed using a recycle procedure. However, the results using this particular method for CO oxidation may not lead to a good correlation with cyanogen chloride retention. |
