Abstract
A non-destructive test has been developed to monitor the impregnants in charcoal. A study of some commercially-produced and custom-made ASC-whetlerites indicates significant increases in the measured magnetic susceptibility from that of the base charcoal. Correlations between the measured susceptibilities and the concentrations of copper and chromium by a linear mathematical model are established with reasonably good fit for the custom-made charcoals. It is concluded that the magnetic susceptibility data would be best utilized as a qualitative tool for the assessment of metal impregnants on charcoal, rather than for precise quantitative analyses. Some preliminary data on the magnetic susceptibilities of ASC-whetlerites co-impregnated with TEDA are also presented. TRUNCATED
