Study on energy saving technique of bamboo biobleaching based on water resource protection

In order to eliminate colour difference of bamboo sheets and prevent bamboo moldy, the energy saving biotechnique of bamboo bleaching rapidly based on water resource protection was studied. The results showed that The H₂O₂ concentration on the impact of white degree was significant at 0.05 level. And white degree increased at first, then decreased with concentration of H₂O₂. the best concentration of H₂O₂ was 3%. The treatment time on the impact of white degree was significant at 0.05 level. And white degree decreased with treatment time. the best treatment time was 0.5h. White degree was bad with white degree longer in the H₂O₂ high concentration solution. Temperature had no significant effect on the bleaching of bamboo. White degree decreased at first, then increased with temperature. the best temperature 90°C. Concentration of the extractives from camphor tree´s leaves had no significant effect on the bleaching of bamboo. White degree decreased at first, then increased with concentration of the extractives from camphor tree´s leaves.
