摘要

研究了粉单竹的竹沥液对半纤维素返黄的影响，用AFM和XPS分析半纤维素表面微观形貌和表面化学成分的变化情况，为研究高得率竹浆的返黄提供依据。实验结果表明，添加竹沥液至从粉单竹中分离出来的半纤维素，其颜色加深，由白色变为浅褐色，SEM和AFM分析发现半纤维素表面吸附着竹沥液物质，而紫外光老化处理后，XPS图谱发现光氧化引起半纤维素表面的竹沥液物质结构发生变化。研究认为竹沥液中的物质沉积在半纤维素表面上会降低竹浆白度，光老化后增加竹浆返黄程度。

Abstract

The effect of succus bambusae on bamboo hemicellulose yellowing was studied.Their surface morphology and chemical composition were characterized by AFM (atomic force microscope)and XPS (or ESCA

electron spectroscopy for chemical analysis)

which can provide the basis for obtaining high-yield of bamboo pulp yellowing.The results showed that the color of hemicellulose separated from raw material changed from white to light brown after adding succus bambusae into it

due to the adsorption of succus bambusae on the hemicellulose surface as indicated by SEM and AFM

and that the structure of succus bambusae on the surface hemicellulose could be varied by UV-light irradiation as demonstrated by XPS.So

the deposition of succus bambusae materials on the hemicellulose surface can decrease whiteness of bamboo pulp

while photo-aging can extend hemicellulose yellowing of bamboo pulp.
