Trace metals have been concentrated onto activated charcoal by using oxalic acid, iminodiacetic acid, and 8-hydroxyquinoline. The charcoal was directly analyzed in an ICP by placing several particles in
a direct sample insertion (DSI) cup, or fabricating a DSI probe with an activated charcoal cap. Detection limits in the tens to hundreds of parts per trillion were found for Pb, Cd, Zn, and Cu. The recovery
for C u was 2-5% but may be improved by reactivation of the plasma-cleaned charcoal. Cleaning the charcoal, derived from wood, in the plasma prior to adsorption was necessary to remove trace metals.
