Summary

The concept of animal protein utilization aiming to reduce leaching of treatment salts from wood was tested and verified. Animal proteins in the form of spray-dried animal blood plasma were used as an addition to the water solution of fungicidal salt or included in the solution for soaking pre-treated wood. The wood was subjected to thermal treatment which caused protein denaturation, a process which changes the proteins' spatial conformation and reduces their solubility in water. Scots pine wood (Pinus sylvestris L.) was treated with a water solution of copper sulfate using vacuum, vacuum-soaking and vacuum-pressure methods. The animal proteins were added to the treatment solutions or applied by soaking to samples pre-treated with the salt. After treatment, the samples were heated to 100°C. After suitable conditioning, the wood was subjected to leaching. The content of Cu2+ in the water extracts was determined by Atomic Absorption Spectrophotometry (AAS).
