Titanium dioxide nanoparticles (TiO2 NPs) are currently one of the most prolifically used nanomaterials, resulting in an increasing likelihood of release to the environment. This is of concern as the potential toxicity of TiO2 NPs has been investigated in several recent studies. Research into their fate and behaviour once entering the environment is urgently needed to support risk assessment and policy development. In this study, we used a multi-method approach combining light scattering and field-flow fractionation techniques to assess both the aggregation behaviour and aggregate structure of TiO2 NPs in different river waters. Results showed that both the aggregate size and surface-adsorbed dissolved organic matter (DOM) were strongly related to the initial DOM concentration of the tested waters (i.e. R(2) > 0.90) suggesting that aggregation of TiO2 NPs is controlled by the presence and concentration of DOM. The conformation of the formed aggregates was also found to be strongly related to the surface-adsorbed DOM (i.e. R(2) > 0.95) with increasing surface-adsorbed DOM leading to more compact structures. Finally, the concentration of TiO2 NPs remaining in the supernatant after sedimentation of the larger aggregates was found to decrease proportionally with both increasing IS and decreasing DOM concentration, resulting in more than 95% sedimentation in the highest IS sample.

“…All samples showed fast absorption of water within the initial 24 hr, followed by gradual decrease until achieving a saturated point (stable behavior). The efficient reinforcement of the samples under investigation is visible from the swelling degree graph (18) . To investigate more precisely the effect of inter-copolymer compound formation on the release of coagulating ingredient, the results were analyzed according to the following equation (19) ( .…”

HITOSAN/ polyacrylic acid membranes containing different ……amounts of Al 2 (SO 4 ) and/or TiO 2 were prepared. The prepared membranes were characterized by measuring mechanical properties, such as tensile strength and elongation at break, swelling properties, antimicrobial and blood clotting. The results obtained indicate that the presence of Al 2 (SO 4 ) and TiO 2 in the membrane formulations has an incremental effect on the antimicrobial properties and blood clotting in albino rates.
