3d Flowerlike Micro/Nanocomposite Ceria To Remove Arsenic And Chromium In Drinking Water, Taera Kim

Honors Theses

Ceria has received great attention for the removal of water contaminants due to its high oxygen storage capacity, marked oxygen ion conductivity, and tunable catalytic activity. Zhong et al. suggested that ceria (cerium oxide) microspheres with nanoscale 3D flowerlike morphology represent a promising inorganic synthetic material to remove water contaminants such as As(V) and Cr(VI) from drinking water. The 3D flowerlike micro/nanocomposite ceria offer key advantages over other nanoparticle based remediation systems as they can be easily removed via conventional microfiltration. The goals of this thesis project were to test the reproducibility of the synthesis of the 3D flowerlike ceria, …
