Coupling of Advanced Oxidation and Adsorption Processes onto Silica-Titania Composites for Low Level Capture of Metals from Water Effluents
Goals and Objectives
In order to adequately protect aquatic ecosystems as well as human health, efforts have focused on decontamination of natural aquatic systems and wastewater containing elevated toxic metals. Commercially available sorbents for metal removal from water simply transfer a liquid-phase pollution problem to a solid waste problem. Furthermore, they are incapable of achieving effluent concentrations in low ppb and/or ppt range. The goal of this project was to investigate the effectiveness of a novel regenerable material, Silica-Titania Composites (STC) for removal of toxic metals from water. The STC technology is robust and can be easily tailored, thus having the potential of treating metal-laden water from a variety of sources (e.g., urban wastewater, industrial process, etc.). Our long-term objective is to target metals in the current EPA's priority pollutants list, but for this seed grant program, we will focus on mercury (Hg) as a case study.
