This Small Business Innovation Research (SBIR) Phase I project will focus on the development of novel environment-friendly nanoporous materials that can effectively absorb and thus remove arsenic from ground water at a very low cost, while providing a means for the safe disposal of the spent arsenic-containing materials. This will be accomplished by (1) preparing the nanoporous geopolymer materials by employing a patented, sustainable, and energy- and materials-efficient production method; (2) characterizing and improving the arsenic absorption capacity of the materials; and (3) examining the arsenic leaching behavior of the spent materials after stabilizing the materials through heat treatment at various temperatures. The broader/commercial impacts of this research are (1) providing to the rural areas in the US and to the arsenic-ridden areas in developing countries, such as Bangladesh and India, an environment-friendly, cost-effective and easy-to-operate arsenic removal technology solution, and (2) providing to the environmental remediation industry a new class of materials that may be utilized in removing other water contaminants, such as heavy metals. The success of this research is critical in meeting the stricter requirement for arsenic in drinking water recently set by the US EPA, and also in helping foreign countries eradicate arsenic poisoning, one of the most devastating environmental disasters in the world. The novel material will be offered to replace the existing sorbent media, will provide performance/cost benefits for residential and commercial systems, and will enable a new water treatment plant design with both cost and environmental advantages.

该小型企业创新研究（SBIR）第一阶段项目将专注于开发新型环保纳米多孔材料，这些材料可以有效地吸收并以极低的成本从地下水中去除砷，同时提供安全处置含砷废料的方法。 这将通过以下方式实现：（1）通过采用专利的、可持续的、能源和材料效率高的生产方法制备纳米多孔地质聚合物材料;（2）表征和提高材料的砷吸收能力;（3）通过在不同温度下热处理稳定材料后，检查废料的砷浸出行为。这项研究的更广泛/商业影响是：（1）为美国农村地区和发展中国家的砷污染地区（如孟加拉国和印度）提供一种环境友好、成本效益高且易于操作的除砷技术解决方案，以及（2）为环境修复行业提供一类可用于去除其他水污染物的新材料，比如重金属。 这项研究的成功对于满足美国环保署最近制定的饮用水砷含量更严格的要求至关重要，也有助于帮助外国消除砷中毒，这是世界上最具破坏性的环境灾难之一。 该新型材料将用于替代现有的吸附剂介质，为住宅和商业系统提供性能/成本效益，并将实现具有成本和环境优势的新水处理厂设计。
