Fulvic acid is also known as fulvic acid, yellow humic acid (mineral). It is an extremely complex black organic substance with bioactive properties, which is the ultimate aerobic breakdown of all living matter, and it has the unusual properties and ability to change and transform molecular combinations, containing almost all organic and inorganic matter in nature. It also has the properties of fusion molecules. It is the ultimate micro-structure after decomposition of all living organisms, and its structure also contains potential solar materials, which are derived from photosynthesis, and solar energy helps to promote the special properties and biological activity of fuluric acid. Fulvic acid deposits are the result of microbial decomposition of large amounts of vegetation. It's a naturally occurring organic substance that comes entirely from decaying ancient plants and animals. Lacking in modern food crops, it is extremely important for human physiological activity. Fulvic acid is by far the most excellent organic acid found in nature. It is part of the humus structure in a fertile compost soil and is extremely scarce. It has acidic properties, and only under undisturbed primeval forests can millions of beneficial microorganisms produce very small amounts of fulvuric acid in a soil environment containing decomposed 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 by the human body and the best health care effect.

As a photosensitizer, fuluric acid can absorb ultraviolet light or solar radiation to produce a series of photoactive substances. Studies have found that fuluric acid can produce some short-lived and strong oxidizing active substances under the radiation of sunlight. OH, produced? OH can oxidize organic pollutants that are slowly degraded by direct photodegradation or cannot absorb ultraviolet or sunlight degradation, promoting the degradation of these substances. In addition, HS can also produce other active substances (ROS) under light, including --22O/HO, -2O, 1O2, H2O2, triwire HS (3HS*) and -aqe, etc. These photoactive substances can change the migration and transformation of organic pollutants existing in water bodies. In particular, for some substances that do not absorb sunlight and are not easy to directly photodegrade, they can cause chemical changes under the action of photoactive substances, affecting their environmental fate and ecological impact, and have a certain role in promoting the photodegradation of organic pollutants. Fulvic acid, as a kind of humus, is a kind of natural photoactive ingredient. After absorbing light, a series of free radical reactions can occur, sensitize organic pollutants in water, and promote the degradation of these organic pollutants to a certain extent.
