US-Turkey Cooperative Research: Preparation of Nanoscale Magnetite Dispersed Polymer Particles for Environmental Applications

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的Arun Sengupta博士和土耳其伊斯坦布尔耶尔德兹技术大学化学工程系的Ulker Beker博士共同开展的一项研究项目。合作的主要领域将包括用于被动环境监测的磁性活性聚合物颗粒（MAPPs）的制备和表征。部分磺化的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。MAPPs的一部分将被送到土耳其的Beker博士那里，她将使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，用MAPPs进行一系列吸附平衡研究。用不同批次的mapp进行多个循环的吸附研究。丙醇将用作脱附的再生剂。随后，这些mapp将由Beker博士带到利哈伊大学。不同循环后MAPPs的磁化率将在Lehigh大学测定，并与母体MAPPs的磁化率进行比较。所得的吸附等温线信息以及磁化率数据将有助于评估MAPPs作为可回收被动监测剂的有效性。范围：该项目将允许一名美国科学家与一名土耳其科学家在环境应用纳米粒子开发领域进行合作。这项研究可能会导致技术上重要材料的发展，以及环境清理产品的开发，特别是对环境危害的清理，如废物中的有机物和金属离子。该项目将包括培训一名美国研究生。国际科学和工程办公室以及化学和运输系统司为这个项目提供资金。

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.
