Composition of fulvic acids after the mechanical activation of peats

摘要

It was found that a structural rearrangement related to a change in the amount of functional groups in the composition of fulvic acids occurred upon the mechanoactivation of peat: the amount of oxygen-containing groups and unsubstituted aliphatic structures increased. Carboxyl groups at the aromatic rings of fulvic acids are most reactive; this fact is responsible for their role in sorption and detoxification processes.
