Title: Quantification of metals in preservatively-treated lumber using laser induced breakdown spectroscopy

Description: The laser induced breakdown spectroscopy (LIBS) technique was evaluated for its capability of quantifying CCA in preservative-treated wood. The results of the study reveal that the LIBS technique can be used to predict the amount of preservative based on chromium peak analysis, but further refinement of the process is necessary before the technique is practiced. The largest variation measured by the LIBS system is the result of heterogeneity in the wood matrix, specifically between transitions corresponding with earlywood and latewood growth.

Keywords: Analytic chemistry, quantitative analytics, recycling, arsenic, wood preservatives, metals, chromium, weathering, copper, preservatives, chromated copper arsenate, preservative treated wood, treated wood, CCA, laser induced breakdown spectroscopy, LIBS
