NITROHUMIC ACID - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| overview | 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 produce soluble humate. It has dispersing and emulsifying effects. Because it contains carbon, hydrogen, oxygen, nitrogen and other elements, but also contains hydroxyl, carbonyl, carboxyl, quinone, methoxy and aromatic core and other active groups, so it has weak acidity, hydrophilicity, complexation, oxidation and reduction, ion exchange and physiological activity. According to its formation process, it is 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 socellic acid (soluble in acetone, ethanol), fulvic acid or fulvic acid (soluble in water). It exists in humus and low-grade coal of soil. Formed by partial decomposition of plant residues in the presence of air and water. It can be extracted from peat, lignite or some soil. Used as soil conditioner, plant growth stimulant, insecticide, fertilizer, herbicide, medicine, oil drilling mud stabilizer and ion exchanger, etc., also used in battery plate, etc. Its sodium salt or ammonium salt is used as a binder for pulverized coal to make humic acid briquettes. |
| drilling fluid | humic acid is the effective component of mud loss reducer coal lye. It is not a single compound, but a mixture of multiple compounds with different molecular sizes and inconsistent structural composition. These compounds contain nitrogen, hydrogen, oxygen, carbon and other elements. From the analysis of functional groups and structures, it is proved that they are multi-functional chain polymer compounds containing aromatic rings and ethylenic bonds. These functional groups have carboxyl groups and alcohol hydroxyl groups., Phenol hydroxyl, methoxy, quinone oxy, nitrogen-containing groups, etc. Carboxyl, phenolic hydroxyl and methoxy groups play the main role as mud treatment agents. The molecular weight ranges from 1900 to 4900, for example: humic acid is cheap, has a wide range of sources, and its temperature resistance can reach 180 to 190 ℃. It is not used directly to treat mud, but in the form of sodium salt. Because it contains a series of active functional groups, it can be modified to further improve the ability to resist mild and pollution. |
| Formation | It is mainly accumulated in the swamp zone after the death of ancient plants. Through complex biochemical and physical chemical changes, the plant remains undergo decarboxylation and dehydration reactions, releasing gaseous products such as carbon dioxide, water and methane, forming a new brown condensate-peat, in addition to a large amount of water, peat also contains a large amount of humic acid and asphalt. |
| Molecular structure | Humic acid molecule is a large complex composed of several similar structural units, each of which is composed of aromatic nuclei, bridge bonds and active groups Three main parts. Aromatic nuclei are usually composed of 5~6 benzene rings or heterocyclic rings, mainly benzene rings, naphthalene, anthraquinone, furan and pyridine. The bridge bonds connecting the aromatic core of humic acid include single bridge bonds and double bridge bonds, including-O-,-CH2-,-S-,-N-, etc. The aromatic core of humic acid has several active groups, mainly phenolic hydroxyl group, carboxyl group, methoxy group, alcohol hydroxyl group, enol group and carbonyl group. These active groups have weak acidity, hydrophilicity, ion exchange, complexation, redox and high adsorption properties. The molecular weight of humic acid ranges from hundreds to tens of thousands, which increases with humification and color deepening. Humic acid alkali metal salts and ammonium salts are soluble in water, and their alkaline earth metal salts are hardly soluble in water. Trivalent metals and heavy metal salts are basically insoluble in water. Raw coal with high calcium and magnesium content can be pickled first and then alkaline washed before humic acid can be extracted. Humic acid first occurs before it is dissolved in lye, and the concentration is reduced to become a solution, which can transmit light, can pass through a semi-permeable membrane, has good stability, and can be stored for a long time. After adding electrolyte to sodium humate solution, it causes colloidal flocculation. In a certain period of time, the minimum amount of electrolyte required for flocculation of a certain amount of humic acid is called flocculation limit. Flocculation limit decreases with increasing shrinkage. |
| element composition | humic acid is mainly composed of carbon, hydrogen, oxygen, nitrogen and other elements, of which carbon content is 52% ~ 65%, hydrogen content is 5% ~ 7%, oxygen content is 25% ~ 40%, nitrogen content is about 3% ~ 4%, and also contains a small amount of phosphorus and sulfur. In humic acid, the proportion of black humic acid is the highest, the proportion of brown humic acid is less, and the proportion of yellow humic acid is the least, accounting for about 2% of the yield of humic acid. The carbon content of brown humic acid is not more than 52% and the oxygen content is not more than 40%. The carbon content in black humic acid is not less than 52% and the oxygen content is not more than 40%. The elemental composition of humic acid is related to sedimentary environment, organic matter type and thermal evolution degree. Humic acid in water has high hydrogen and nitrogen content and low carbon content. In the peat-lignite-weathered bituminous coal series, the humic acid carbon content increases and the oxygen content decreases. |
| classification | humic acid is usually divided into three categories: soil humic acid, water humic acid and coal humic acid. The content of soil humic acid and water humic acid is very low, and the content of coal humic acid is high and has industrial development value. Coal humic acid can be divided into primary humic acid and secondary humic acid according to its existence mode. Humic acid that exists in natural substances such as peat and lignite is called primary humic acid; humic acid formed by weathering or artificial oxidation of coal is called regenerated humic acid. According to its solubility and color, it can be divided into yellow humic acid (a group of humic acids with a smaller molecular weight, generally yellow, soluble in water, dilute acid, alkali solution and acetone), brown humic acid (a group of humic acids with a medium molecular weight, generally brown, soluble in dilute caustic solution and acetone or ethanol, insoluble in dilute acid) and black humic acid (a group of humic acids with a larger molecular weight, generally black, soluble in dilute caustic solution, insoluble in dilute acid, acetone and ethanol). According to the different binding states, it can be divided into free humic acid (humic acid with acidic groups remaining in a free state, including humic acid combined with potassium and sodium in the actual determination, usually expressed by HAf) and bound humic acid (acid The humic acid that binds to metal ions does not include humic acid combined with potassium and sodium in the actual determination, usually expressed by HAc). The sum of free humic acid and bound humic acid is total humic acid, usually expressed as HAt. |
| humic acid fertilizer | humic acid is an organic compound produced by animal and plant residues under the action of microorganisms. The fertilizer with it as the main ingredient contains a lot of organic matter and has multiple functions of farm fertilizers. Humic acid fertilizers contain a variety of complex effective ingredients, which can improve the quality of crops, increase disease resistance, and improve wheat resistance to drought, The ability to resist dry and hot wind has obvious effects. When it is tried in Jiangxi Province, the yield of rice can be increased by about 18%; in Yunnan Province, after the application of humic acid fertilizers to rice, corn, millet, rape, tobacco and other crops, the minimum yield can be increased by about 20%, and the maximum yield can be increased by about 40%. The application of humic acid fertilizers can also improve the quality of crops. Tests in Zhanjiang, Guangdong Province have proved that the protein of rice applied with humic acid fertilizer increased by 1.6 ‰, fat increased by 1.5 ‰, and starch increased by 0.9 ‰. The quality of peanuts, sugarcane, lychees, etc. that have been applied with this fertilizer has also improved. the main varieties of humic acid fertilizers are: ammonium humate, sodium humate, ammonium nitro humate, nitrohumic acid and humic acid nitrogen, phosphorus and potassium compound fertilizers. Weathered coal and peat are indispensable for the production of base materials. Henan is rich in coal resources and has a large reserves of weathered coal, which has the basic conditions for the development of humic acid fertilizers. Although there was development in the 1970s, the production scale was small, the technology was backward, and the products could not meet the quality standards and use requirements. Most of these enterprises had stopped production. natural humic acid is widely distributed in nature, including soil, compost, manure, peat lignite and weathered coal. The use of humic acid fertilizers has become a new type of fertilizer with rich sources, simple manufacturing methods, low investment, large harvest, and promising development. In recent years, the development of humic acid fertilizer industry has risen again, but it has not yet formed a scale. |
| uses and functions | humic acid is mainly used as oil drilling mud treatment agent in industry. Humic acid sulfonate is used as an anionic surfactant for concrete engineering and coal water slurry preparation; sodium humate-soda ash is used for scale inhibition in water jackets of low-pressure boilers, steam locomotives and automobiles; sodium humate is used as ceramic mud Additives can improve the yield and product quality; it can be used as a non-toxic beneficiation inhibitor and a precipitant for rare earth metals in beneficiation; it can also be used as a briquette binder, humic acid granular ion exchanger can treat cadmium cyanide plating wastewater, chromium-containing and nickel-containing electroplating wastewater and industrial zinc-containing wastewater. Humic acid can be used in agriculture to improve soil or adjust the pH in soil; it has a synergistic effect on chemical fertilizers; it has a stimulating effect on plant growth. Since the 2070s, China has done a lot of basic research and clinical trials on the application of humic acid in medicine, indicating that it has a certain effect on anti-inflammatory, antipyretic, analgesic and improving human microcirculation and endocrine function. In terms of animal husbandry, sodium humate is mainly used as a feed additive to promote the growth of livestock and prevent animal gastrointestinal diseases and diarrhea.
