摘要
对玉米秸秆、猪粪、泥炭、风化煤中类胡敏酸(HLA)的数量、色调系数、相对色度、活化度等性质进行了初步的比较研究。结果表明:HLA的数量及其占全部可提取的类腐殖质数量的比例为:风化煤>泥炭>猪粪、玉米秸秆,说明风化煤的腐殖化程度最高,其次为泥炭,猪粪、玉米秸秆的腐殖化程度最低。HLA的色调系数(△logk)和活化度为:玉米秸秆、猪粪>泥炭>风化煤,相对色度(RF)的顺序与此相反,说明玉米秸秆、猪粪中HLA的脂族性最强,分子结构最简单;其次为泥炭,而风化煤HLA的脂族性最弱,分子结构最复杂。
Some properties of humic-like acids (HLA) from corn stalk, pig manure, peat and weathering coal were studied. The results showed that the proportion of HLA in total extractable humic-like substance was weathering coal > peat > pig manure, corn stalk. It was the same as the order of humification degree . △logk and activation degree of HLA, being corn stalk, pig manure > peat > weathering coal. It indicated that HLA from corn stalk and pig manure was simple, while HLA from weathering coal was complex in their molecular structure.
