Application
As a photosensitizer,fulvic acidcan produce a series of photoactive substances by absorbing ultraviolet light or solar radiation. Research has found thatfulvic acidcan produce some short-lived and strong oxidizing active substances -OH under the radiation of sunlight. The generated OH can oxidize organic pollutants that are slow to be degraded by direct light or cannot be degraded by ultraviolet light or sunlight, 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 water The migration and transformation of existing organic pollutants, especially for some substances that do not absorb sunlight and are not easy to directly undergo photodegradation, can cause chemical changes under the action of photoactive substances, affecting their environmental fate and ecological impact , It has a certain promotion effect on the photodegradation of organic pollutants.
As a kind of humus,fulvic acidis a kind of natural photoactive component. It can undergo a series of free radical reactions after absorbing light, sensitize the organic pollutants in the water body, and have a certain promotion effect on the degradation of these organic pollutants.
synthesis method
| Introduction | Fulvic acid is also called fulvic acid and yellow humic acid (mineral origin). It is an extremely complex black organic substance with biologically active characteristics. It is the ultimate aerobic decomposition product of all living substances. It has unusual characteristics and capabilities, can change and transform molecular combinations, and contains almost all organic and inorganic in nature. substance. At the same time, it has the characteristics of a fusion molecule. It is the ultimate microstructure after all active biological decomposition, and its structure also contains potential solar substances, derived from photosynthesis. Solar energy helps promote the special properties and biological activities of fulvic acid. Fulvic 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 rotting ancient animals and plants. Lacking in modern food crops, it is extremely important for human physiological activity乐动体育最新版本. Fulvic acidis by far the best organic acid found in nature. It is part of the humus structure in a fertile compost soil, and the content is extremely scarce. It has acidic properties. Only in the virgin forest without human interference, millions of beneficial microorganisms can produce a very small amount of fulvic acid in a soil environment containing decomposed plant materials and sufficient oxygen. Fulvic acid is a kind of 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 the human body, and has the best medical and health effectsPAC. 富里酸被称为一个优秀的电解质。It can replenish more than 70 kinds of minerals and trace elements needed by the human body, promote the body’s acid-base balance, remove free radicals, complex heavy metals, detoxify pollutants, enhance immunity, and activate beneficial cells.PAM. |
| Chemical nature | Studies have found that fulvic acid has a lower molecular weight. Compared with humic acid, its molecular structure contains less carbon and more oxygen, and its acidic functional group (-COOH) content is also higher than that of humic acid. In addition, the number of ketone carbonyl groups and hydroxyl groups contained in fulvic acid is also higher than that of humic acid. Therefore, compared with humic acid, it has stronger acidity in aqueous solution. At present, the specific molecular structure of fulvic acid is not very clear. Based on the humus carbon skeleton structure, the structure model of a certain fulvic acid is 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%. |
