腐植酸是一种无定型的、多种高分子物质的混合物,目前对其真实的分子结构还不了解。通常呈黑色或棕色的胶体状态,其干燥时外形呈贝壳断口的凝胶状,密度在1．330-1．448g／cm3之间,具有很大的比表面积,在稀溶液条件下像水一样无粘性。以下是腐植酸的一些基本性质。
Humic acid is an amorphous, a mixture of a variety of polymer materials, the current molecular structure of its real unknown. Usually black or brown colloidal state, the appearance of the shape of shellfish fracture when dry gel, the density between 1.330-1.448g / cm3, with a large specific surface area, under the conditions of dilute solution like water No sticky. The following are some of the basic properties of humic acid.
