摘　　要：研究了在木素氧化酶催化的体系下,木素前驱物松柏醇-β-D-葡萄糖苷-[α-13C]与废水中的木素碳水化合物复合体反应的方法及其机理。采用13C同位素示踪技术,并结合红外谱图分析、核磁共振技术来探讨松柏醇葡萄糖苷与废水中木素碳水化合物复合体的聚合产物的化学结构。同时应用GPC分析手段测定了聚合产物的相对分子质量Mn。研究表明:木素前驱物松柏醇-β-D-葡萄糖苷能与废水中LCC发生脱氢聚合反应,同时GPC测定的结果表明聚合后相对分子质量也明显增大,Mn从11320上升到23810~36886。The mechanism of polymerization between eoniferin and Lignin-Carbohydrate Complex in the efflu ents from paper mill Catalyzed by lignin oxidase was studyed, FT-IR and Isotopic technology, combined with ^13 C-NMR technology were applied to investigate the chemical structure of the obtained polymer. At the same time GPC was used to analyze the molecular of the polymerization products. The result indicated that eoniferin-[ a - ^13C] can polymerize with LCC by dehydrogenation. While GPC determination proved the increase of Mn from 11320 to 23810 ～ 36886. Polymerization products of Lignin-Carbohydrate Complex precipitated. This reaction can be used to reduce Lignin-Carbohydrate Complex concentration of effluents to reduce the pollution duty of the effluent from paper mill.
