Development of Nanoporous Geopolymer Composites as Adsorbent for Arsenic Removal Development of Nanoporous Geopolymer Composites as Adsorbent for Arsenic Removal After the US government has set the arsenic standard for drinking water at 10 parts per billion and required all water systems to comply with this standard, an innovative unit materials/process has been sought after not only to increase the removal efficiently at lower capital cost, but also to address the concerns with high operation cost, water stream contamination and problematic disposal situation. , a Tempe-based clean-tech company, has recently licensed from ASU an exclusive option for the production method of nanoporous geopolymer composites which was invented by the PIs research lab. Based on the new technology, the company seeks to develop new cost-effective adsorbent for arsenic removal, with a financial support from the US NSF through its SBIR Program. We have successfully completed the Phase I deliverables (award # 1046473) in Jan-June 2011 and propose to continue the work as described in Phase II proposal. If funded, the Phase II project will start on January 1, 2012 and last for 18 months. The PI and co-PI will provide their expertise in materials synthesis, characterization techniques, pilot-production and pilotscale testing of the novel adsorbent that are essential for the success of the project. The first objective of the Phase II project is to demonstrate the successful pilot production of Fe-npGEOTM (iron-impregnated nanoporous geopolymer); The second objective is to validate improved performance of novel adsorbent media in a pilot testing configuration; The third objective is to continuously improve the new nanoporous geopolymer composites, and characterize their pore and crystalline structures, material composition, and surface properties; The fourth objective is to perform efficient evaluation of newly developed media using established multi-dimensional evaluation methodology; The fifth objective is to identify and resolve Fe-npGEOTM production / deployment barriers if any.
