This study was conducted to determine the presence of the insecticide permethrin and its retention gradients within the structure of laminated bamboo after treatment using supercritical carbon dioxide (SC-CO 2 ) as the carrier solvent. the presence of permetrin was based on functional group differences indicated by FT-IR analyses before and after the preservative treatment. Permethrin retentions in the treated bamboo materials ranged from 0.0020 to 0.0022%. This result indicated that the preservative treatment of laminated bamboo using SC-CO 2 as a carrier solvent produced evenly distributed chemical an effective level. There was no signicant distribution gradient of the preservative observed over the layers of the treated laminated bamboo arranged with outer-inner surface laminations. The current treatment condition is potential to produce laminated bamboo products completely resistant to biodegradation.
