0647137 Shah智力优点：研究进行：在研究进行到目前为止，从资金产生卡特里娜研究，我们已经建立了概念验证，并开发了水处理系统的实验室原型。该方法相当简单，处理是在一个非常系统的方法进行如下：过渡金属（铜）被固定在聚合物基质和聚合物-金属络合物浸入污染的水体。然后加入过氧化氢。在上述程序后孵育污染物导致污染物水平降低。实验结果表明，该系统对不同类型细菌污染的水进行处理，在15 min内细菌负荷降低99.9%以上。 65%的多环芳烃被去除污染的水在一个小时内培养。原型成功地测试了从新奥尔良获得的洪水。拟议的研究：通过拟议的研究，PI将采取的目标是向前迈出一步，并扩大技术处理100 L的污染水。在拟议研究的第一步，我们将修改催化剂，使开发的催化剂在性能和特性上与现场使用的催化剂相匹配。在第二步中，将进行研究以在将其插入污染水中之前开发带电催化剂。这样做是为了消除向水中加入过氧化氢。在第三步中，目前针对1 mL优化的工艺将扩大到100 L容量。尺寸分析将用于按比例放大工艺参数。在这些研究中，人工洪水将被创建，将包含E。大肠杆菌细胞（1 × 107个细胞/mL）、萘（0.5 ppm）、铅和砷（10 ppm）。通过各种优化研究，我们将开发聚合物，铜和过氧化氢的最佳组合。最终浓度为500 E.大肠杆菌细胞/ml、0.05 ppm萘和0.1 ppm铅和砷或更少将被视为成功去污。治疗时间不超过6小时。

0647137ShahIntellectual Merit: Research carried out: In the research carried out so far from the funding of the resulting Katrina research, we have established proof-of-concept and developed a laboratory prototype of the water treatment system. The method is reasonably simple and treatment is carried out in a very systematic methodology as follows: transition metal (copper) is immobilized on the polymer matrix and the polymer-metal complex is immersed into the contaminated water body. Hydrogen peroxide is then added. Incubating the contaminated after above procedure results in reduction of contaminants level. Results show that water contaminated with various types of bacteria was treated with the developed system and bacterial load reduced by more than 99.9 % in 15 minutes. 65% of PAHs were removed from contaminated water within one hour of incubation. The prototype was successfully tested on floodwater obtained from New Orleans.Proposed research: Through the proposed research the PI will take aim to take a step forward and scale up the technology to treat 100 L of contaminated water. In the first step of the proposed research, we would modify the catalyst such that the developed catalyst would match in property and characteristics to that used in the field. In the second step studies will be carried out to develop charged catalyst before inserting it in contaminated water. This would be done to eliminate the addition of hydrogen peroxide into water. In the third step, the process, which is currently optimized for 1 mL, will be scaled up to 100 L capacity. Dimensional Analysis will be used to scale up the process parameters. In these studies artificial flood water will be created that would contain E. coli cells (1 x 107 cell/mL), naphthalene (0.5 ppm), lead and arsenic (10 ppm). Through various optimization studies we would develop the best combination possible of polymer, copper and hydrogen peroxide. Final concentration of 500 E. coli cells/ml, 0.05 ppm of napthalene and 0.1 ppm of lead and arsenic or less will be considered as successful decontamination. Treatment time will not exceed 6 hours.
