Removal copper, chromium and arsenic from CCA-treated yellow pine by oleic acid

Removal of Cu, Cr and As metals from chromated copper arsenate (CCA) treated yellow pine wood samples with three different dimensions were investigated by extraction with oleic acid at four different pH levels. The concentrations of Cu, Cr and As were determined by XRF. The effects of pH, dimension...

Description
Summary:Removal of Cu, Cr and As metals from chromated copper arsenate (CCA) treated yellow pine wood samples with three different dimensions were investigated by extraction with oleic acid at four different pH levels. The concentrations of Cu, Cr and As were determined by XRF. The effects of pH, dimension and duration on remediation of CCA-treated wood samples were determined. Oleic acid was found to be very effective to remove copper, chromium and arsenic from CCA-treated wood samples especially at lower pH levels (pH=2.00 and 2.50). In addition, the best models estimate copper, chromium and arsenic leaching from CCA-treated wood samples by oleic acid remediation were determined by step-wise regression analysis.
