Simple and rapid identification if there is fulvic acid in potassium fulvic acid
At present, there are many products called fulvic acid containing potassium fulvic acid or potassium humate on the market. A lot of friends asked me, if there is no very good test conditions, how to know if his product really contains fulvic acid? In fact, as long as we understand the characteristics of fulvic acid, we can simply identify whether the product contains fulvic acid or not. This kind of character is known as qualitative in chemistry. Of course, quantitative will require rigorous testing to know. Mineral source fulvic acid is the least molecular weight component in humic acid products, which can dissolve in both acid and alkali. Other acids like black humic acid and brown humic acid are insoluble in acid , and we can use this feature to simply identify whether the humic acid product you buy contains fulvic acid. Methods: 0.1 g product was dissolved into 1000ml water (tap water and purified water), diluted 10000 times, add a small amount of sulfuric acid (o...
