The chemical and physical characteristics of humic acids (HA) vary depending on their source, age, and soil conditions. Ideally, the extraction method should not modify the characteristics of HA. Hydrofluoric acid (HF) is often used in HA extraction methods to remove inorganic constituents present in natural soil samples. However, there are concerns that using such a powerful reagent as HF may change the properties of HA.
