摘要：

Titanium dioxide nanoparticles (TiO2 NPs) are an emerging environmental concern, considering their proven toxicity and wide commercial application nowadays. Once entering natural water bodies, they might become a challenge to conventional water treatment techniques. In this pioneering study, coagulation was found to achieve 86 % of concentration removal and 74% of turbidity removal of TiO2 NPs in natural lake water, when the initial concentration was 1 mg L-1 and the corresponding turbidity was 2.3 NTU. Furthermore, the zeta potential seemed not to be the only decisive factor in the coagulation effect. Further studies on the clarification of the mechanisms involved are hence recommended.
