| 摘 要： | 对四种来源不同的腐植酸(张家口褐煤、大同褐煤抽提腐植酸、黄县褐煤、黄县黑页岩氧化腐植酸)进行了工业分析、元素分析、官能团、光密度、凝聚限度、分子量、红外和~1H-NMR等化学和物理方法的测定,为其应用研究提供基础数据。结果表明,四种腐植酸的组成结构有较大差异,其中以张家口褐煤腐植酸具有较多的脂碳结构,分子量较小,具钠盐县有最低的表面张力。

| Abstract: | The proximate analysis,elemental analysis functional groups,extinction,coagulation value,average molecular weight,infrared and 1H-NMR spectra of four hurnic acids from Zhangjiakou and Datong brown coals,oxidized Huangxian brown coal and black oil shale were determined.The four hurnic acids differ considerably from one another in chemical composition and properties.Among them,the humic acid from Zhangjiakou brown coal is of more aliphatic structure,lower molecular weight and the surface tension of its sodium salt is the lowest. |
