办公废纸酶法脱墨浆滤液还原糖离子色谱分析
Ion Chromatographic Analysis of Reducing Sugar in Enzymatic Deinking Filtrate of Mixed Office Waste
【摘要】 在混合办公废纸脱墨过程中,不同特性的纤维素酶使纤维素降解产生还原糖的情况是不同的,文章利用离子色谱对此进行了分析研究。在实验条件下,纯的内切酶对纤维不产生降解;内切酶与外切酶协同作用(FPA/CMCase为0.029时),纤维被降解产生一定量葡萄糖、纤维二糖等还原糖,这不利于酶脱墨浆纤维的强度;木聚糖酶对办公废纸纤维的降解作用甚微。
【Abstract】 Through ion ehroraatographie analysis to different cellulases, the change of reducing sugar in filtrate during enzymatic deinking of mixed office waste were studied. The results showed that pure endoglucanases did not hydrolyze fiber. But the synergetic effect of the endoglucanases and cellobiolhydralases(FPA/CMCase=0.029)could hydrolyze fiber to some extent, and produce some glucose,cellobiose etc., which was harmful to fiber intensity. Xylanases had little influence to the intensity of mixed office waste fiber.
