腐植酸(FA)是一大类弱酸性化合物的总称,根据提取的工艺、分离的手段不同,得到的腐植酸类化合物的聚合度、分子量不同。当腐植酸与金属离子、铵等成盐后,可用于不同的用途。由于腐植酸具有极为特殊的物理化学性质和生物活性,如腐植酸与蛋白、胨、肽、氯基酸等的结合率很高、具有强螯合能力,对生物体免疫系统、营养平衡、体内能量转换具有的调节作用等,因此,世界各国各行业都 Humic acid (FA) is a general term for a large group of weakly acidic compounds. According to the extraction process and the means of separation, the degree of polymerization and the molecular weight of the obtained humic acids are different. When humic acid and metal ions, ammonium and other salt, can be used for different purposes. Because humic acid has very special physicochemical properties and biological activity, such as humic acid and protein, peptone, peptide, chlorine and other high binding rate, with strong chelation ability, the body’s immune system, nutritional balance, in vivo Energy conversion has the regulatory role, therefore, all over the world in all industries
