Effects of Alkaline Extraction on Micro/Nano Particles of Eucalyptus Camaldulensis Biology
As the most planting tree species in South China, Eucalyptus camaldulensis wood has been main fiber materials for preparing degradable composite materials. However, wood extractives and hemicellulose were nearly complete dissolved out in preparation of the fiber, resulting in more serious water pollution and meanwhile bring a great waste of biological resources. Thereby, in order to find out the leaching rule of micro/nano particles from Eucalyptus camaldulensis wood, Eucalyptus camaldulensis wood was treated in alkaline solutions at room temperature and the extractives obtained was analyzed by Sizer. The results were following as: (1) Different alkali, its concentration and extraction time have a significant different influence on the particles leaching with the different diameters. And the KOH, NaOH, LiOH all had impacts on the volume fraction and number fraction of leached particles and the significance reduced in turn at the same other conditions. (2) The optimum concentration of KOH, NaOH and LiOH was 17.5%, 18.5% and 15.0% at room temperature, respectively. The optimum extraction time of the untreated samples was 20 h, 24 h and 24 h, respectively. The optimum extraction time of the pretreated samples was 16 h, 16 h and 12 h, respectively.
