Study of Humic Acids Fractionation
Original language description
Humic acids (HA) are natural compounds which cannot be characterized by chemical formula. They are not chemical individual but a heterogenous mixture of various organic compounds. HA are traditionally defined according to their solubility in alkaline solutions. In previous work it was confirmed that it is possible to subdivide HA into their fraction by dissolving in buffer solution with various pH. In this contribution some organic solvents were used for HA fractionation. In view of HA unique structurevarious polar and non-polar solvents were chosen for this study. Obtained fractions were characterized by several analytical methods. Composition and structure of individual fractions are compared and discussed.
