采用超滤法将腐殖酸（HA）分离成不同分子量的组分，并采用多元素分析、UV 254/TOC、FT-IR和三维荧光光谱等方法对HA进行了表征。由于不同分子量的腐殖酸具有不同的亲水性和分子大小，碱性离子交换树脂的最大吸附量出现在分子量为6000 - 10，000 Da的腐殖酸上。
In this paper, humic acid (HA) was ultra-filtered into different molecular weight sections and was characterized by multi-element analysis, UV254/TOC, FT-IR and three-dimensional fluorescence spectrometric. Since humic acids of different molecular weights have different hydrophilic and molecular size, the maximum adsorption capacity of basic ion exchange resins appears on the humic acid whose molecular weight ranges from 6000 to 10,000Da.
