| 摘 要： | 本文对L-阿拉伯糖、D-木糖、D-甘露、D-半乳糖、D-葡萄糖的糖晴乙酰化衍生物进行了气相色谱分析.实验选择了最佳色谱分离条件,用以OV-210与ECNSS-M为固定液的混合柱,使衍生物分离效率提高了3-6倍,同时找到了最佳内标物-木糖醇,提高了定量分析的速度及准确度.在建立标准分析方法的同时,论文对草浆蒸煮废液的预处理方法进行了摸索,建立了最佳水解条件,以糖腈乙酰化法将单糖衍生化.实验结果表明,经厌氧发酵后造纸废液中几乎无碳水化合物,发酵前废液中碳水化合物以低聚糖形式存在.并测定了发酵前后废液中各种单糖的浓度.

| Abstract: | Nitrile acetyl derivatives of saccharides involving L-Arabinose D-Xylose D-Mannose D-Galactose and D-glucose were determined with gas chromatography under optimum conditions, the employment of a mixed column of fixed liquids composed by ov-210 and ECNSS-M, proved to have upgraded separation efficiency 3-6 fold. To attain faster and more accurate quantitative determinations, Xylitol was found to be a highly efficient internal standard, pretreatment of straw pulping waste liquor involeed the optimization of its hydrolysis, to yield nitrile acetyl derivatives of its saccharide contents. Experimental results indicated that carbohydrates were practically non-existent in the anaerobic treated waste liquor. It was noted that all carbohydrates existed as low molecular weight polysaccharose. Concentrations of monsaccharose before and after anaerobic treatment of the waste liquor were determined. |
