CBET-0829092CannonNumerous U.S. groundwater sources host unacceptable levels of perchlorate, nitrate, chromate, vanadate, etc. Available processes for removing these contaminants generally invoke use of petrochemical-based ion exchange media or membranes, which force municipalities and their suppliers to rely on non-renewable raw materials that are mined from non-sustainable and uncertain sources. The investigators are targeting to devise means of employing instead lignocellulosic biomaterials (biocarbons) that originate naturally from within America. The team will build on their recently-devised means of functionalizing the porous biocarbons with reduced-nitrogen groups that remove perchlorate and other oxyanions. The project will link into the Sloan Fellowship program for Minority Ph.D. candidates at Penn State, which is co-led by PI Dr. Cannon. There will also be participation in Penn State's CURO program, which facilitates minority undergraduate research.

许多美国地下水资源含有不可接受的高氯酸盐、硝酸盐、铬酸盐、钒酸盐等。去除这些污染物的现有工艺通常需要使用基于石化的离子交换介质或膜，这迫使市政当局及其供应商依赖于从不可持续和不确定来源开采的不可再生原材料。研究人员的目标是设计出一种方法来代替天然产自美国的木质纤维素生物材料（生物碳）。该团队将以他们最近设计的方法为基础，通过还原氮基团使多孔生物碳功能化，从而去除高氯酸盐和其他氧离子。该项目将与宾夕法尼亚州立大学斯隆少数族裔博士奖学金项目相关联，该项目由PI Cannon博士共同领导。他们还将参与宾夕法尼亚州立大学的CURO项目，该项目旨在促进少数民族本科生的研究。
