Abstract
Thermal lens spectrometry was compared to spectrometry of the diphenyl carbazide chromophore and to atomic absorption spectrometry for the qu antification of hexavalent chromium after extraction from CCA-treated building timbers with sodium carbonate-sodium hydroxide solution. Agre ement among the results indicates that thermal lens spectrometry is ap plicable to the quantification of hexavalent chromium in this matrix.
