Frontiers of Environmental Science & Engineering 2019, Volume 13, Issue 5, doi: 10.1007/s11783-019-1163-y

Abstract: Deposition was reduced at higher pH and by adsorption of phosphate in soil.Surface roughness and charge heterogeneity play a role in the deposition/ release.However, the influence of phosphate on deposition/release— and thereby on transport— of TiO2 NPs in soilResults show that the deposition of TiO2 NPs decreased with decreasing IS, increasing pH, and when soilAccordingly, both primary- and secondary-minimum deposition were inhibited.
