摘要
从云南中甸沼泽土中提取了腐殖酸样品 ,并对样品的性质进行了测定。结果表明 :用稀碱法提取的腐殖酸含有羧基、醇羟基、酚羟基等多种活性官能团 ,具有较大的比表面积 。
Humic acid was extracted from swampy soil in Zhongdian at Yunnan and characterized. Experiments show that the extracted humic acid has many active groups in its structure, such as carbonyl, hydroxy, carboxyl and phenolic groups. It has large external specific surface. This method is effective and simple.
