摘要：

The influences of four types of dilute acid washing (H2SO4, HCl, HF, HNO3) on moso bamboo pyrolysis were investigated via pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS). The effects of acid washings on the inorganics contents and the chemical structure were also analyzed. The results indicated that all the acid washings could effectively remove a large portion of inorganics and disrupt the chemical structure to a certain extent. HCl-washing behaved the best in removing inorganics and had the most marked disruption effect on bamboo structure. Acid washings promoted the bamboo pyrolysis and increased the contents of both phenols and sugars. HCl-washing had the most significant promotion effect on the levoglucosan formation with the absolute peak area increasing from 8.12 x 10(8) to 1.92 x 10(9). The absolute peak areas of 2,3-dihydrobenzofuran decreased more or less after acid washings. All the acid washings except H2SO4-washing could significantly increase the absolute peak area of methoxyeugenol. (C) 2015 Elsevier Ltd. All rights reserved.
