腐植酸是一种含有芳香环的无定形的高分子化合物,通常呈黑色或棕色的胶体。在高倍显微镜下观察,腐植酸分子具有一种含众多空隙的疏松的“海棉状”结构,有很强的持水性和吸附性能,在工业上可被用作吸附剂、钻井泥浆稀释剂、铅蓄电池中作铅电极的扩张剂和硬质胶中的填充剂等。 Humic acid is an amorphous, macromolecular compound containing an aromatic ring, usually colloidal in black or brown. Under high magnification microscope, the humic acid molecule has a loose “sponge” structure with many voids, has strong water-holding property and adsorption property, and can be used industrially as adsorbent, drilling mud thinner, Lead-acid batteries for the expansion of lead electrodes and hard plastic filler and so on.
