Study of surface and solution properties of gemini-conventional surfactant mixtures and their effects on solubilization of polycyclic aromatic hydrocarbons

► The present study is useful to understand the mixing effect on solubilization. ► Single and binary systems of cationic gemini and conventional surfactants were studied. ► Above cmc, water solubility of PAHs increases linearly by the surfactant systems. ► Maximum solubilization occurs in the Brij 58 surfactant micelles. ► Solubility enhancement of organic pollutants by mixed systems can extend scope of SER.
