GOALI: US-Native Biomaterials, Nitrogen-functionalized to Adsorb Perchlorate and other Oxyanions from Water

CBET-0829092加农炮许多美国地下水源含有不可接受水平的高氯酸盐、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从非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，使用来自美国的天然木质纤维素生物材料（生物碳）。 该团队将建立在他们最近设计的功能化多孔生物碳的方法上，减少氮基团，去除高氯酸盐和其他含氧阴离子。 该项目将与斯隆少数族裔博士奖学金项目挂钩。宾夕法尼亚州立大学的候选人，这是由PI博士共同领导坎农。 还将参加宾夕法尼亚州立大学的CURO项目，该项目促进了少数民族本科生的研究。

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.
