Fate and transport of engineered nanoscale titanium dioxide (nTiO2) have received much attention during the past decade. The aggregation and stability of nTiO2 in water with complicated components, however, have not been fully examined. The objective of this paper is to determine the individual and synergistic effect of cation valence, humic acid, and clay colloids on nTiO2 stability and aggregation, and elucidate the related mechanisms. We conducted systematic laboratory experiments to… CONTINUE READING
