Transport of TiO2 nanoparticles through water saturated packed columns
(2014) Chrysikopoulos Constantinos; Χρυσικοπουλος Κωνσταντινος; I.D. Manariotis; D. Vassilopoulos
In this work, various TiO2 NP suspensions were prepared using different preparation techniques. Rutile-anatase and anatase TiO2 NPs were used for the preparation of aquatic NP suspensions at various concentrations. Measurements of particles size and zeta potential were performed in order to investigate the effect of sonication and aging on nanoparticle agglomerates. Finally, transport experiments of TiO2 NP solutions in packed columns were performed for varying TiO2 concentrations. The concentration and size of the NPs were measured at the outlet of the column. It was observed that a substantial percentage of the NPs injected into the experimental column were retained in the column packing.
