In order to overcome the above-mentioned negative effects, the fresh Chinese-fir shavings were extracted in KOH soultion, were analyzed by ZETA and SIZER to find out the leaching rule of nano particles in Chinese-fir wood. The results are as follows: (1) The extraction mass arrived at the maximum value when KOH concentration is about 17.5%. The micro/nano particles in Chinese-fir shavings would be...
The extractives from masson pine (Pinus massoniana L.) bark has been used in medicine successfully. Therefore, Py-GC/MS was used to analyze the high-grade resource recovery of benzene/ethanol extractives of masson pine wood. Relative content of each component was determined by area normalization. The main and abundant constituents of 590deg pyrolysis product of masson pine wood werel-phenanthrene...
The extractives from masson pine (Pinus massoniana L.) wood would not only consume bleaching agent and other additives, but also aggravate environmental pollution. Therefore, Py-GC/MS was used to analyze the high-grade resource recovery of acetone extractives of masson pine wood. Relative content of each component was determined by area normalization. The main and abundant constituents of 590degC...
