Fulvic acid - Reference Information

| what is fulvic acid | fulvic acid is also called fulphora acid and yellow humic acid (mineral source). It is an extremely complex black organic substance with biologically active characteristics. It is the ultimate aerobic decomposition of all living substances. It has unusual characteristics and abilities, can change and transform molecular combinations, and contains almost all organic and inorganic substances in nature. At the same time, it has the characteristics of fusion molecules. It is the ultimate microstructure after the decomposition of all active organisms. Its structure also contains potential solar substances, which are derived from photosynthesis. Solar energy helps promote the special quality and biological activity of fulvic acid. Fulic acid deposition comes from the decomposition of a large amount of vegetation by microorganisms. It is a naturally occurring organic substance that comes entirely from decaying ancient animals and plants. Lack of modern food crops is extremely important to human physiological activity. Fulvic acid is the best organic acid found in nature so far. It is part of the humus structure in a fertile compost soil, and its content is extremely rare. It has acidic properties. Only under the virgin forest without human interference, millions of beneficial microorganisms can produce a very small amount of fulvic acid in a soil environment containing decomposing plant matter and sufficient oxygen. fulvic acid is a humic acid with high oxidation degree, small molecular weight, many active functional groups, soluble in acid, alkali and water, easy to be absorbed and utilized by human body and the best effect of medical care. |
| Structure | Studies have found that fulvic acid has a lower molecular weight. Compared with humic acid, its molecular structure contains less carbon, more oxygen, and Its acidic functional group (-COOH) content is also higher than humic acid. In addition, the number of ketone carbonyl and hydroxyl groups contained in fulvic acid is also higher than that of humic acid, so compared with humic acid, it has strong acidity in aqueous solution. At present, the specific molecular structure of fulvic acid is not very clear. Based on the carbon skeleton structure of humus, a structural model of fulvic acid is obtained as shown in Figure 1. The carbon content of fulvic acid is generally between 40% and 50%, the hydrogen content is between 4% and 6%, and the oxygen content is between 44% and 50%. |
| excellent electrolyte | fulic acid is called an excellent electrolyte, which can supplement more than 70 kinds of minerals and trace elements needed by human body, promote acid-base balance of human body, scavenge free radicals, complexate heavy metals, detoxify pollutants, enhance immunity and activate beneficial cells. Electrolyte is a substance that is easily soluble in water or other suitable electrizable media. The rebirth of electrolyte is called "beautiful demonstration" and "perfect experiment" by scientists ". In many tests, when the energy of the electrolyte is removed, it will cause the cell to rupture and die; reintroduce the electron energy and become active again. The potential is zero when a person dies. These studies confirm that the proper absorption of electrons is of great help to the health of plants, animals and human beings. Fulic acid has been proven to be a powerful organic electrolyte to balance cell life. |
| action | fulvic acid, as a photosensitizer, can produce a series of photoactive substances by absorbing ultraviolet light or solar radiation. studies have found that fulvic acid can produce some active substances that exist briefly and have strong oxidizing properties under the radiation of sunlight? OH, produced? OH can oxidize organic pollutants that are slow in direct photodegradation or cannot absorb ultraviolet light or solar light degradation, and promote the degradation of these substances. In addition, HS can also produce other active substances (ROS) under light, including -- 22O/HO,-2O,1O2,H2O2, triplet HS(3HS *) and-aqe, etc. These photoactive substances can change the migration and transformation of organic pollutants existing in water bodies, especially for some substances that do not absorb sunlight and are not easy to directly degrade, under the action of photoactive substances, it can cause chemical changes, affect its environmental destination and ecological impact, and promote the photodegradation of organic pollutants to a certain extent. Fulicic acid, as a kind of humus, is a kind of natural photoactive ingredient. It can undergo a series of free radical reactions after absorbing light, sensitizing organic pollutants in water, and producing certain promotion effect on the degradation of these organic pollutants. |
