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、核磁共振技术探讨了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。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,从11320上升到23810～36886。反应生成聚合产物为木素-碳水化合物复合体大分子而沉淀析出,在废水中水溶性、难降解木素的LCC可被有效地去除,使废水的污染负荷降低。The mechanism of polymerization with coniferin and Lignin-Carbohydrate Complex in the effluents from paper mill Catalyzed by lignin oxidase was investigated. The chemical structure of the obtained polymer was characterized by FT-IR and Isotopic technology, combined with ^13C-NMR technology. GPC was used to analyze the molecular of the polymerization products. The result indicated that coniferin-[α-^13C] can polymerize with LCC by dehydrogenation. GPC determination proved that the Mn increased of from 11320 to 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 charge of the effluent from paper mill.
