【摘要】 从草炭、褐煤、风化煤3种腐殖化程度不同的物料中提取了3种不同的胡敏酸,分别对其进行酒精分级,并 对各级分的碳、氮含量进行了测定.结果表明,在3种胡敏酸中,草炭胡敏酸的脂肪性最强,芳构化度最低,分子量 最小;风化煤胡敏酸的脂肪性最弱,芳构化度最强,分子量最大;褐煤胡敏酸则居中.更多还原

【Abstract】 In has made study on the alcohol fraction of humic acid that extracted from peat,lignite and weathering coal. Meanwhile, the content of humic acid ,carbon and nitrogen of every fraction were determined. The experimental results showed that the aromatization degree of peat HA was the lowest, successively with lignite HA and weathering coal HA.更多还原
