Abstract
Arsenic contamination in groundwater is a severe global problem most notably in Southeast Asia where millions suffer from acute and chronic arsenic poisoning Removing arsenic from groundwater in impoverished rural or urban areas without electricity and with no manufacturing infrastructure remains a significant challenge Magnetite nanocrystals have proven to be useful in arsenic remediation and could feasibly be synthesized by a thermal decomposition method that employs refluxing of FeOOH and oleic acid in 1octadecene in a laboratory setup To reduce the initial cost of production US 2600/kg and make this nanomaterial widely available we suggest that inexpensive and accessible “everyday” chemicals be used Here we show that it is possible to create functional and highquality nanocrystals using methods appropriate for manufacturing in diverse and minimal infrastructure even those without electricity We suggest that the transfer of this knowledge is best achieved using an open source conceptWe thank NSF for its support of the Center for Biological and Environmental Nanotechnology EEC0647452 We also acknowledge with gratitude the Office of Naval Research N000140410003 and the US Environmental Protection Agency Star Program RD832536010 for funding CTY thanks the Robert A Welch Foundation ©1342 for a graduate fellowship CTY would like to thank the organizers of the International Congress on Production of Safe Water January 2123 2009 Izmir Turkey for the invitation
