XRF, EDX, IR analysis was conducted to figure the effect of Fe to blacken the waterlogged wood. The results showed that investigated soil contained more Fe than normal soil by XRF analysis and wood ash contained more sulfur and Fe than any other element by EDX analysis. C-H and C-O peaks were significantly reduced at the surface of wood where is blackened part of waterlogged wood by IR analysis. The optimum condition to remove Fe from waterlogged wood by EDTA was investigated. To do this, removed concentration of Fe was measured at various concentration of EDTA-2Na. The optimum pH of EDTA-2Na was figured to be 4.1 to 4.3 and as the concentration of EDTA was increasing, extracted concentration of Fe was also increased. In the case of 0.4 wt% of EDTA-2Na, 700ppm of Fe was eliminated and was stabilized after 48 hours time lapse. In the case of EDTA-3Na, the optimum pH was 7 to 8, and 10 ppm of Fe was eliminated at 0.4 wt% of EDTA-3Na. In the case of EDTA-4Na, the optimum pH was 10 to 11, and 120 ppm of Fe was eliminated at 0.4 wt% of EDTA-4Na.
