Research Abstract

Microspectroscopic analysis showed promise as a means of chemical state analysis of copper in wood treated with copper-based preservatives. It also enabled the analysis of copper microdistribution and concentration in wood before/after leaching in the same location within the same specimen. Copper nanoparticles ranged in size from 20 to 700 nm could penetrate the porous microstructure of wood and were abundantly present in pit chambers and on tertiary wall layers adjacent to the lumens of tracheids and ray parenchyma cells. Furthermore it was supposed that smaller copper nanoparticles were able to penetrate tracheid cell walls.
