This Small Business Innovation Research (SBIR) Phase II project will build on the successful results obtained during Phase I. Phase I research indicated that aqueous chlorine can be used as an alternative chemical source for Advanced Oxidation Processes (AOPs), and was capable of producing hydroxyl and other highly reactive radicals when illuminated with ultraviolet light. These radicals were harnessed to destroy and mineralize small organic molecules and impact the structure of natural organic matter found in surface water. Phase II research will focus on developing a solid understanding of how aqueous chlorine based AOPs can be integrated into overall water treatment processes, compare the efficacies of aqueous chlorine and hydrogen peroxide based AOPs, and demonstrate that solar ultraviolet light can be used to drive this process.The broader impacts of this research center around the ability to provide a greener, more efficient AOP which can be used to more economically produce high quality water. Phase II research will deliver an increased understanding of chlorine-based AOP technology, enabling the development of products with enhanced capabilities towards the removal of trace organic contaminants from water. Successful completion of this research will positively impact the quality of both drinking water and packaged beverages. In addition, the research could permanently remove contaminants from the environment through mineralization, preventing unintended release from municipal and industrial wastewater plants. Finally, since this process can be driven using solar energy, the resulting technology will be deployable in rural and developing regions of the world at an affordable cost.

这个小企业创新研究（SBIR）二期项目将建立在第一阶段取得的成功成果的基础上。第一阶段的研究表明，氯水可以用作高级氧化过程（AOPs）的替代化学来源，并且在紫外线照射下能够产生羟基和其他高活性自由基。这些自由基被用来破坏和矿化小有机分子，并影响地表水中天然有机物质的结构。第二阶段的研究将侧重于深入了解基于氯水的AOPs如何整合到整个水处理过程中，比较基于氯水和过氧化氢的AOPs的效率，并证明太阳紫外线可以用来驱动这一过程。这项研究的更广泛的影响集中在提供更绿色、更有效的AOP的能力上，这种AOP可以更经济地用于生产高质量的水。第二阶段的研究将加深对基于氯的AOP技术的理解，从而开发出具有增强功能的产品，以去除水中的微量有机污染物。这项研究的成功完成将对饮用水和包装饮料的质量产生积极的影响。此外，该研究可以通过矿化永久清除环境中的污染物，防止市政和工业废水厂的意外排放。最后，由于这一过程可以利用太阳能驱动，由此产生的技术将以可承受的成本在世界农村和发展中地区部署。
