Abstract EN
Various factors affect the sedimentation behavior of nanotitanium dioxide (n-TiO2) in water.
Accordingly, this study aimed to select the dominating factor.
An index of sedimentation efficiency related to n-TiO2 concentration was applied to precisely describe the n-TiO2 sedimentation behavior.
Ionic strength (IS), natural organic matter (NOM) content, and pH were evaluated in sedimentation experiments.
An orthogonal experimental design was used to sequence the affecting ability of these factors.
Furthermore, simulative sedimentation experiments were performed.
The n-TiO2 sedimentation behavior was only affected by pH and NOM content at low levels of IS.
Moreover, divalent cations can efficiently influence the n-TiO2 sedimentation behavior compared with monovalent cations at fixed IS.
Seven different environmental water samples were also used to investigate the n-TiO2 sedimentation behavior in aquatic environments.
Results confirmed that IS, in which divalent cations may play an important role, was the dominating factor influencing the n-TiO2 sedimentation behavior in aquatic environments.
