Interaction and binding of dissolved orthophosphate on insoluble complexes of marine humic substances and calcium, magnesium, iron and aluminium have been studied. The results pointed out that solubility of metalhumic and fulvic complexes increases as the pH of the suspension increases with strong phosphorus fixation at pH-values between 4 and 6. The possible mechanism of this binding involves formation of a complex association in which metal ions bound to the humic substances act as a bridge between humic macromolecules and phosphate anion.
