Effects of Hot Water Post Treatment on Accelerating Copper Fization in ACQ-D Treated Chinese Fir

摘要：

Introduction Due to the growing pressure from environmental concerns, chromated copper arsenate (CCA), which had been used widely before, have been replaced by copper based wood preservatives such as alkaline copper quat (ACQ) in many countries. These copper based preservative systems do not contain arsenic or chromium which would bring great risk to human health and environmental safety. However, many studies showed that Cr(VI) could oxidize various lignocellulosic groups to form strong fixation sites for copper and form insoluble copper chromate CuCrO4 in the matrix (Pizzi 1982, Lebow et al. 2002, Stook et al. 2005). As the result of the absence of chromate, the active ingredient copper is inclined to leaching while exposed outdoors.
