A comparison of the leaching resistance of copper 2-ethanolamine and copper ethylenediamine treated Scots pine

Xiao Jiang, J N R Ruddick
The depletion of copper from copper 2-ethanolamine and copper ethylenediamine treated Scots pine blocks was investigated. A greater leaching resistance was found for copper 2-ethanolamine, which retained ca. 86% and ca. 50% copper after water and buffer leaching, respectively. Leached amine treated blocks also contained significant residual amine. This was consistent with other observations linked to the formation of amine acid salts in amine treated wood. The results also suggested that significant loss of copper, due to formation of copper acetate can occur.
