Sodium humate is a kind of sodium salt of humic acid. It is a kind of weak acid sodium salt of biological macromolecular organic chemistry, which is made of lignite, albino low calorific value peat and smoky lignite as raw materials after special crushing, according to the biological fermentation technology, and then to high temperature polymerization production and processing.

Sodium humate is a kind of relatively stable natural biological macromolecular mixture organic substance with aromatic structure. Sodium humate is a kind of strong alkali and weak acid salt. It has the bidirectional properties of physical adsorption and organic chemical adsorption at the same time, and has high reaction activity and strong adsorption performance. Its physical adsorption is like activated carbon, and it can absorb the odor in water and some fine impurities in reverse. After sodium humate dissolves water, it will exist in the form of humic acid positive ions and sodium ions. When there are divalent and trivalent cations such as aluminum ion or lead positive ion in water, humic acid will re complex with high valence cation to produce a kind of complex humic acid salt which does not dissolve water, thus reducing the metal cadmium positive ion in water. The adsorption capacity of humic acid can effectively improve the natural environment of water and reduce the positive metal cadmium ions, so it can achieve the effect of purifying water quality in practical application.
