| Abstract: | 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. |
