摘要
从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 :用焦磷酸钠和氢氧化钠混合液一次提取的腐殖酸含有羰基、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 on Yunnan.Its Characteristic was studied.Experiment show that the extracted humic acid has much active structure,such as carbony,hydroxy,carboxyl and phenolic group.It has major external specific surface. This method is an effective and simple way.
