A generalized description of aquatic colloidal interactions: the three-colloidal component approach
Article Abstract:
Colloidal interactions in aqueous solutions are found to vary and that the concentration of stable colloids are dependent on the relative proportions of fulvic compounds, compact inorganic colloids and rigid biopolymers. Fulvic compounds are found to stabilize organic colloids while rigid biopolymers are found to have a destabilizing effect with the formation of aggregates dependent on the amount of each in an aquatic system.
