Development of micellar structures in solutions of surfactants may increase the apparent aqueous solubility of polycyclic aromatic hydrocarbons (PAHs). In this study, we tested the effect of the structures of humic acids and their derivates on the enhancement of solubility of six polycyclic aromatic hydrocarbons. Solubility of PAHs in presence of humic acids increased with increasing number of aromatic rings. Similar results demonstrated anionic surfactants with and without aromatic rings. The modified humic substances demonstrated more significant solubilizing effect of PAHs.
