摘要: 木质素是天然高分子聚合物,具有一定的化学反应惰性。本文率先研究草类木质素在膜助电解时的电化学氧化作用。其结果表明:膜助电解对黑液中的有机物具有一定的氧化作用,能使木质素中的芳环被氧化而打开;同时木质素的氧化作用与施加的电压、阳极的电极材料等因素有关。通过对木质素氧化产物结构的进一步研究,可为木质素的电化学改性提供了新的方法。

Abstract: Lignin are natural polymers with inertness of reaction.In this paper,research on electrochemical oxidation of grass lignin by membrane assisted electrolysis was carried out for the first time both at home and abroad.Result showed that aromatic rings of lignin are opened by electrochemical oxidation,and oxidation of lignin is closely related to the electrode material and electric voltage.Further study on the structure of the lignin oxide could provide a new way to modify the electrochemical property of lignin.

Key words: membrane-assisted electrolysis, lignin, electrochemical oxidation
