Abstract: Arsenic contamination in groundwater is a serious threat to human health due to its chronic toxicity and carcinogenicity. To meet stringent standards for arsenic in drinking water that have been established by the US EPA, new treatment technologies are needed. The objective of this research is to develop and characterize novel adsorbents for this purpose. Nanoporous titania and nano-sized titania incorporated mesoporous silica (i.e., Ti-SBA-15) will be investigated. Specific tasks to be accomplished in this research are: synthesize nanoporous adsorbents, determine kinetics of arsenic removal, determine equilibrium characteristics of arsenic removal, optimize conditions for arsenic removal, and determine capacity of nanoporous adsorbents to be regenerated. Preliminary results show that these nanoporous adsorbents are likely to have desirable characteristics for application in water treatment processes.
