Leaching of copper from wood preserved with these solutions is still higher than leaching from wood impregnated with copper chromium ones. In order to decrease leaching, different carboxylic acids (octanoic, 2-ethylhexanoic, decanoic) were added to copper/amine/boron aqueous solutions. An experiment of leaching of copper from Norway spruce was performed according to the modified standard procedure (EN 1250). Results confirmed that carboxylic acids significantly improve copper fixation. The best fixation was determined in specimens impregnated with the preservative solutions consisting of copper, ethanolamine, boric acid and octanoic acid. From such wood, only 1.6% of copper was leached.</dc:description><dc:date>2005</dc:date><dc:date>2015-07-10 11:43:04</dc:date><dc:type>Delo ni kategorizirano</dc:type><dc:identifier>33593</dc:identifier><dc:language>sl</dc:language></rdf:Description></rdf:RDF>
