- The sorption properties of TiO2 nanoparticles (NPs) on sand were investigated in the presence of Suwannee River humic acid (SRHA) as a surrogate for natural organic matter. SRHA drastically reduced the sorption preference regardless of the initial pH and ionic strength of the solution. Despite the higher SRHA loading onto sand versus the TiO2 NPs, the consequent zeta (f)-potential drop was more significant in the TiO2 NPs, indicating that the decreased sorption should be primarily ascribed to the fraction of SRHA sorbed onto the TiO2 NP surfaces. The hindering effect of SRHA on the sorption increased with SRHA concentration, but stabilized at the concentration equivalent to full surface coverage of the TiO2 NPs and sand in the reaction system.
