【摘要】 本文对微生物降解褐煤产生的腐植酸的化学特性进行了分析.结果表明,褐煤经微生物降解后其腐植酸与降解前相比.氢和氧百分含量增加,碳百分含量减少,分子量减小,而絮凝极限明显增大,红外吸收光谱也发生明显变化更多还原

【Abstract】 Chemical properties of humic acid of lignite degraded by Penicillium sp. have been studied. After degraded by Penicillium sp. the humic acids had higher content of H and O, but lower content of C, its molecular weight was decreased, while the flocculation limit was increased distinctly, the IR spectra were also changed compared with the humic acids of original lignite.更多还原
