Theses and Dissertations
Nonmetallic Arsenic and hydrocarbon BTEX are the most common and harmful contaminants in groundwater. Many oxide, biological and metal based adsorbent materials have been investigated in the laboratory and in the field environment. These materials, especially for nano-TiO2, have been extensively studied in the laboratory due to its high efficiency and remediation outcomes. This research compared two different synthetic nano-TiO2, aggregated dendritic nano-scale anatase TiO2 and the polymorphed rutile nano-TiO2 attached to the surface of SiO2, to study the feasibility of nano-TiO2 in geoenvironmental engineering applications. Characterization of crystal structure, purity, and morphologic, microscopic features of the materials were examed …
