Unlike the fixation of CCA preservative, where the rate of fixation reaction is slowed down by evaporative cooling during drying, delayed drying of ACQ treated wood had no observable effect on the copper fixation rate. However, at 50 degrees C, delayed drying resulted in a higher degree of copper fixation, while this effect was not observed at 22 degrees C. Post-treatment of ACQ treated wood with pressurized CO2 immediately after treatment, reduced the pH of the solution in wood and resulted in rapid fixation of the copper. However, in time, the pH increased as CO2 dissipated from the solution allowing the copper to re-solubilize.en10.1007/s00107-008-0279-8info:eu-repo/semantics/closedAccessArticle671712WOS:000267042700002N/AQ4
