| 摘 要： | 通过对不同产地，不同提取方法获得的煤炭腐植酸和经过生物发酵人工合成的生化黄腐酸分别进行铝离子絮凝实验和酸化沉淀实验，发现煤炭腐植酸、腐植酸盐、棕惰酸、黄腐酸都同时具有被铝离子定量絮凝和在酸性条件下定量沉淀的特性，这类物质具有极其相近的化学特性。生化黄腐酸在上述两方面显示出与煤炭腐植酸十分不同的特性。

| Abstract: | Through high-valent metal ion flocculation andacidified precipitation on two kinds of humic acid derivingfrom different areas and extracted by different methods,the results slowed that coal humic acid,humicateand fulvicacid can be flocculated quantitatively by high-valent metalions,and precipitated by acid.This kind of materials are simi-lar in chemical property,but BFA is from coal humic acidin the two characteristics. |
