Extraction of chromated copper arsenate from wood wastes using green solvent supercritical carbon dioxide

To provide a green method to remove chromated copper arsenate (CCA) in the wood before its dumping, incineration, reuse or disposal, extraction of CCA from wood wastes using supercritical carbon dioxide (ScCO 2) containing an organophosphorus reagent, Cyanex 302, was investigated. The majority of co...
