Abstract

In this study, the fixation speed of 2% Ce1cure (ACe) preservative in three different temperatures (10,20 and 30.C) in poplar (Populus nigra far. Pyramidalis) wood was examined. The 2 by 2 by 2 cm wood blocks from sapwood and heartwood with 14% moisture content were impregnated with the ce1cure solution. The impregnated blocks then were exposed to different temperatures. In each temerature, the blocks were chosen periodically and squeezed to extract the solution. The extracted solutions were analyzed to determine the concentration of chromium VI using diphenyl carbazide method. The process was continued until 99.8% of chromium is fixed. The results showed that temperature plays an important role in the fixation process. In general, fixation in sapwood was faster than heartwood. The fastest fixation occurred in sapwood at 30.C in 460 hours (19 days) while with the same temperature in heartwood, fixation time was 1132 hours (47 days).
