Influence of Electrochemical Processing on the Dispersed Composition of Humic Compounds

摘要

Abstract A preparation of peat humic acids modified by electrochemical treatment in an alkaline medium on iron electrodes was obtained. The effect of the electrochemical treatment on the dispersed composition of the particles of humic substances was determined using dynamic light scattering (quantum correlation spectroscopy). It was found that humic compounds in solution predominantly occur in the form of agglomerates (130–6000 nm), the dispersed composition of which becomes more homogeneous upon electrochemical treatment, and the ability for associative interactions decreases.
