ABSTRACTCBET-0730050Timothy StrathmannUniversity of Illinois Urbana-ChampaignDevelopment of a sustainable catalytic treatment process for perchlorateThis project will develop new catalysts to reduce perchlorate to chloride in brines produced from the regeneration of ion-exchange resins used in remedial systems. Current use of these catalysts is successful only at pH 3. The PIs will attempt to expand the pH range for reduction of perchlorate into the circumneutral range and reduce perchlorate at ambient temperatures and pressures. The new catalysts contain Pd and Re on supports such as zeolites, activated alumina and functionalized mesoporous silica. Several graduate and undergraduate students will be involved in the research, and the research will be integrated into classroom activities. Teaching modules will be developed for K12 students.

中文摘要：伊利诺斯大学厄巴纳-香槟分校的Timothy Strathmann高氯酸盐可持续催化处理工艺的开发本项目将开发新的催化剂，用于将补救系统中使用的离子交换树脂再生产生的盐水中的高氯酸盐还原为氯化物。目前使用这些催化剂仅在pH 3时是成功的。PI将尝试将高氯酸盐还原的pH值范围扩大到环中性范围，并在环境温度和压力下还原高氯酸盐。新的催化剂含有Pd和Re的载体，如沸石，活性氧化铝和功能化的介孔二氧化硅。一些研究生和本科生将参与研究，研究将融入课堂活动。将为K12学生开发教学模块。
