摘　　要：该研究以产自我国陕西秦巴山区的栓皮栎软木初生皮为原材料,对栓皮栎软木化学除杂技术进行了探索。试验发现,将软木块浸泡于5.82mol/L盐酸溶液与6.12mol/L硫酸溶液体积比4:3的混合溶液中,并在恒温水浴60℃条件下浸泡20h的处理条件下软木除杂效果较优;通过扫描电镜对处理前后软木微观构造的对比观察,发现杂质细胞由之前的排列整齐变为杂乱,细胞间隙增大,且质地变疏松,易被剥离,而软木细胞未发生明显变化,表明此除杂工艺能够对软木产生明显的除杂效果。This study explored chemical methods of impurities removal of primary bark of Quercus Variabilis, which was collected from qinba mountains of Shaanxi. The results show that the optimal socking treatment is mingling of 5.82 mol/L HCL and 6.12 mol/L H2SO4 by volume ratio 4：3, water temperature is 60℃ and socked for 20 hours. The Scanning Electron Microscopy （SEM） micrographs reveal that the arrangement of impurities cells changed from orderliness to unorderliness, cell gap increased and texture loosed, while no apparent changes are observed in cork cells, which show that this impurity removal technology has significant impurity removal effects.
