0217830 Sengupta描述：该奖项是为了支持宾夕法尼亚州伯利恒利哈伊大学土木与环境工程系Arun Sengupta博士和土耳其伊斯坦布尔耶尔迪兹技术大学化学工程系Ulker Beker博士的联合研究项目。 合作的主要领域将包括磁活性聚合物颗粒（MAPP）的制备和表征，用于被动环境监测。 部分磺化聚合物珠将在利哈伊大学使用三步程序制备和磁化。 粒子的磁化率将在利哈伊大学测定。 一部分MAPP将被送往土耳其的Beker博士，她将在那里利用含有氯化碳氢化合物和其他挥发性有机化合物的模拟废水和工业废水，对MAPP进行一系列吸附平衡研究。 将使用不同批次的MAPP进行多个循环的吸附研究。 丙醇将用作解吸的再生剂。 随后，这些地图将由贝克博士带到利哈伊大学。 经过各种循环后，MAPP的磁化率将在利哈伊大学测定，并与母体MAPP的磁化率进行比较。 吸附等温线沿着与磁化率数据的信息将有助于评估MAPPs作为可回收被动监测agents.Scope的有效性：这个项目将允许美国科学家与土耳其科学家在纳米粒子开发领域的环境应用。这项研究可能会导致开发具有重要技术意义的材料，并开发用于环境清理的产品，特别是环境危害，如废物中的有机物和金属离子。 该项目将涉及一名美国研究生的培训。 国际科学和工程办公室以及化学和运输系统司为该项目提供资金。

0217830SenguptaDescription: This award is for support of a joint research project by Dr. Arun Sengupta, Department of Civil and Environmental Engineering, Lehigh University, Bethlehem, Pennsylvania, and Dr. Ulker Beker, Department of Chemical Engineering, Yildiz Technical University, Istanbul, Turkey. The primary area of collaboration will encompass the preparation and characterization of Magnetically Active Polymeric Particles (MAPPs) for passive environmental monitoring. Partially sulfonated polymer beads will be prepared and magnetized in Lehigh University using the three-step procedure. Magnetic susceptibility of the particles will be determined at Lehigh University. One portion of the MAPPs will be sent to Dr. Beker in Turkey where she will carry out a series of sorption equilibrium studies with MAPPs, using both simulated and industrial wastewaters containing chlorinated hydrocarbons and other volatile organic compounds. Sorption studies will be carried out for multiple cycles with different batches of MAPPs. Propanol will be used as the regenerant for desorption. Subsequently, these MAPPs will be brought to Lehigh University by Dr. Beker. Magnetic susceptibilities of MAPPs after various cycles will be determined at Lehigh University and compared with the magnetic susceptibility of the parent MAPPs. The resulting information on sorption isotherms along with magnetic susceptibility data will help evaluate the effectiveness of MAPPs as recyclable passive monitoring agents.Scope: This project will allow a US scientist to collaborate with a Turkish scientist in the area of nanoparticle development for environmental applications. The research could lead to the development of technologically important materials, and to products for environmental cleanups, especially of environmental hazards such as organics and metal ions from waste. The project will involve the training of a U.S. graduate student. The Office of International Science and Engineering and the Division of Chemical and Transport Systems provide funding for this project.
