20.500.12556/RUL-33593 Influence of carboxylic acids on fixation of copper in wood impregnated with copper amine based preservatives The importance of copper/amine based preservatives is increasing. 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. zaščita lesa baker karboksilna kislina true false false Angleški jezik Angleški jezik Delo ni kategorizirano 2015-07-10 11:43:04 2015-07-10 11:43:04 2022-06-21 03:44:29 0000-00-00 00:00:00 2005 0 0 Str. 685-693 no. 8 Vol. 39 2005 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*844 0043-7719 1349257 9151749 https://doi.org/10.1007/s00226-005-0031-z 0 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=33604 Biotehniška fakulteta 0 0 0
