Laboratory Studies on Copper Availability in Wood Treated with Soluble Amine Copper and Micronized Copper Systems
IRG/WP 08-30489L Jin, P Walcheski, A Preston
A laboratory method has been employed to investigate the level of soluble copper in wood treated with various copper-based preservative systems, such as micronized copper (particulate copper) and amine copper solutions. This report describes the methodology and preliminary results on determination of the soluble copper in the treating solutions and the treated wood by these systems, as well as the potential impact on performance of such systems against wood decay fungi.
