Abstract

Wood chemical components are among the most important and effective factors in the FIXATION of water-borne preservatives in the wood. This research investigated the effect of wood EXTRACTIVE on FIXATION and LEACHING of “arsenic copper chromate“ (ACC) preservative in beech (Fagus orientalis) wood blocks. Three groups of wood blocks (control, as wood with EXTRACTIVE, wood pre-extracted with hot water and wood pre-extracted with ethanol acetone) were impregnated with 2% ACC and then were placed in an incubator for 0, 192, 384, 576, and 768 hours at 25oC and 75% humidity. After removal from the incubator, the blocks were extracted and the preservative solution of each block was analyzed. The Cr (VI) of the extracted preservative, as the indication of the fixed amount in wood was analyzed using UV spectroscopy and the Cu and Cr contents was measured by atomic absorption. The results showed that the effect of hot water-soluble EXTRACTIVE on FIXATION and LEACHING of ACC was significant (P<0.01). The lowest content of unfixed Cu and Cr components was detected from control samples which indicate that the EXTRACTIVE imparts positive effect on FIXATION. The percentage of unfixed ACC in control samples was significantly lower than in pre-extracted samples.
