Problems solved by technology

However, many existing fulvic acid extraction methods include: alkali-dissolved acid analysis method, strong acid extraction method, sulfuric acid acetone / ethanol method, catalytic oxygen decomposition method and organic solvent extraction method, etc., the extracted product is relatively rough (fulvic acid Low acid content, high content of other harmful impurities), it is basically difficult to reach food grade
Although Zhang Huifen et al. (Research on the Purification Process of Medicinal Fulvic Acid [J]. Food Industry Science and Technology, 2012, 33(22):296-298.) proposed to use cation exchange resin to further purify the crude extract of fulvic acid, the result It shows that the content of ash and five common harmful elements is significantly reduced, and the activity is relatively enhanced, but it is still difficult to implement large-scale due to the constraints of process efficiency, resin material cost, and consistent operation.
