EAGER: Magnetic Carbon Nanocomposites for Heavy Metal Removal from Polluted Water

1137441磁性碳纳米复合材料（MCCs）结合了磁性和上级吸附能力，在环境修复中发挥巨大作用。这一建议的前提是，具有可控的内在结构的MCCs作为新型吸附剂具有巨大的前景，用于净化含有低浓度重金属的废水，这挑战了目前现有的技术，包括通过单一活性炭吸附。目前对MCNC的环境修复性能几乎一无所知，特别是具有不同碳结构的MCNC。同样重要的是，关于哪种MCNC最适合去除重金属，几乎一无所知。然而，我们的初步研究结果表明，操纵的MCNC可以用来净化废水，通过去除痕量重金属，以满足EPA的requires. This拟议的研究的目的是操纵MCNC与不同的有机-无机杂化物的内在结构，并评估其重金属去除性能。提出了一种新的MCNC辅助磁场辅助过程，以解决中央环境修复技术的挑战。这一过程将易于回收MCNC和重金属。拟议项目的挑战是确定用于重金属去除的最佳MCNC。研究工作分为三个紧密结合的研究方向：（1）从商业和实验室制造的纳米颗粒合成不同的有机-无机杂化物：制备了具有不同物理化学结构的薄膜和纳米纤维;（2）制备了一类新型的具有可控纳米结构的MCNC（3）重金属去除性能测试。这将推进提供下一代多功能吸附剂和提供变革性环境修复纳米技术所需的知识。 我们的工作将对迅速发展的吸附剂领域产生重大影响。MCCs辅助的场助分离工艺将使低浓度重金属废水的处理达到EPA对Cr（VI）释放的要求。与公司的密切联系将促进新的环境纳米技术的快速商业化，并加快服务社会/社区的技术。基础研究为以工程方式探索新型MCCs提供了基础，将化学，化学/环境工程，材料科学与工程以及电化学整合到一个研究主题中。这一跨学科项目将为教育和培训创造许多值得注意的机会。K-12外展，本科教育，国际影响和课程开发进行了详细说明。与行业的紧密联系将带来就业机会。将高度重视代表性不足的女生。

1137441GuoMagnetic carbon nanocomposites (MCNCs) combining magnetic properties and the superior adsorption capability can play an enormous role in environmental remediation. The premise of this proposal is that MCNCs with a controlled intrinstic structure have enormous promise as novel adsorbents for purifying wastewater containing low concentrated heavy metals, which challenges the current existing technologies including the adsorption by sole activated carbon. Almost nothing is currently known about the performance of MCNCs for environmental remediation, especially with different carbon structures. Equally importantly, almost nothing is known regarding which MCNC is best for heavy metal removal. Our preliminary results have demonstrated, however, that the manipulated MCNCs can be used to purify wastewater by removing trace heavy metals to satisfy EPA requirements.The objective of this proposed research is to manipulate intrinsic structures of MCNCs with different organic-inorganic hybrids and to evaluate their heavy metal removal performance. A magnetic field assisted process with the aid of novel MCNCs to tackle the central environmental remediation technique challenge is proposed. This process would be amenable to easy-recycling MCNCs and heavy metals. The challenge of the proposed project is to determine the optimum MCNCs for heavy metal removal. The research efforts are grouped into three closely coupled research thrusts: (1) synthesis of different organic-inorganic hybrids from both commercial and lab-made nanoparticles: both thin films and nanofibers will be prepared, with various physicochemical structures, (2) preparation of a new family of MCNCs with controllable nanostructure (solid, porous and semi-permeable) by the obtained optimum fabrication process (stabilization and carbonization temperature and time), and (3) heavy metal removal performance test. This will advance the knowledge required to provide next-generation multifunctional adsorbents and provide transformative environmental remediation nanotechnology. Our work will make a significant impact on the rapidly developing field of adsorbents. The field assisted separation process with the aid of MCNCs will make the treatment of the wastewater containing lowly concentrated heavy metals satisfying the EPA requirement for the released Cr(VI). The intimate connection with the companies will foster quick commercialization of the new environmental nanotechnology and expedite the techniques in serving society/community. The fundamental studies provide a basis to explore novel MCNCs in an engineering way integrating the chemistry, chemical/environmental engineering, materials science and engineering, and electrochemistry into one research topic. This interdisciplinary project will create many noteworthy opportunities for education and training. K-12 outreach, undergraduate education, international impact and curriculum development are detailed. Strong bondage with industry will bring job opportunity. Underrepresented and female students will be highly emphasized.
