Introduction

Humic acid is also known as humic acid. A complex mixture of natural organic polymer compounds. Black or dark brown amorphous powder, slightly soluble in water and acidic, soluble in hot concentrated nitric acid and dark red. It reacts with alkali solution to generate soluble humate. It has dispersing and emulsifying effect. Because it contains elements such as carbon, hydrogen, oxygen, nitrogen, and active groups such as hydroxyl, carbonyl, carboxyl, quinone, methoxy, and aromatic nuclei, it has weak acidity, hydrophilicity, complexation, redox, etc. sex, ion exchange, and physiological activity. According to its formation process, it can be divided into primary humic acid and regenerated humic acid. According to its solubility and color, it is divided into black humic acid or humic acid (soluble in alkali solution), brown humic acid or oxalic acid (soluble in acetone, ethanol), fulvic acid or fulvic acid (soluble in water) . Exist in humus and low-rank coal in soil. Formed by partial decomposition of plant residues in the presence of air and water. It can be extracted from peat, lignite or some soils. Used as soil improver, plant growth stimulant, pesticide, fertilizer, herbicide, drug, mud stabilizer and ion exchanger for oil drilling, etc., and also used in battery plates, etc. Its sodium salt or ammonium salt is used as a binder for pulverized coal to make humic acid briquettes.

Chemical properties

This product is black powder, non-toxic, tasteless, soluble in water, and the aqueous solution is alkaline.

Use

●  It is used as a high-temperature-resistant and filter-reducing agent for freshwater drilling fluid, and it also has the function of reducing viscosity. But salt resistance is poor.

●  Used as fertilizer and soil acid regulator

●  It is the raw material for the production of humic acid compound fertilizer, and also the raw material for the production of drilling aids and pesticides

●  biochemical research

●  Phytostimulant. There are functional groups such as carboxyl, hydroxyl, carbonyl, quinone, and methoxy attached to the humic acid macromolecule. With metal ion exchange, adsorption, complexation, chelation and so on. As a polyelectrolyte in the dispersion system, it has the functions of coagulation, peptization and dispersion.

Production method

●  Use high-quality lignite to react with caustic soda [lignite: caustic soda = 100: (10-20) (mass ratio)], filter, concentrate and dry the reaction solution to obtain the product.
