Arsenic and chromium based water-borne preservatives,especially CCA（chromated copper arsenate）,have been partly replaced by some copper based preservatives.To improve the poor leaching resistance of water-borne preservatives,this paper presented four approaches to accelerate the fixation of active ingredients in treated wood.It also analyzed the fixation effects of these approaches on the active ingredients of CCA and other preservatives in treated wood,and predicted the future research on how to accelerate the active ingredients of ACQ preservative in treated wood.
