U.S.-Brazil Cooperative Research: Modified Clays in Hazardous Waste Disposal

小行星9415675 这个美国-巴西合作科学计划奖支持旅费和消耗性研究用品的工作将进行的F。卡特利奇和M. Titlebaum，路易斯安那州州立大学（LSU），路易斯安那州，与博士P Buchler，圣保罗，巴西大学。 Cartledge博士、Titlebaum博士和Buchler博士正在研究使用水泥粘合剂固化/稳定危险废物的问题，这是一种适用于废物流（主要是含重金属的废物）的常见技术。 在该方法中使用有机粘土作为添加剂有可能大大扩大该方法的实用性，特别是用于处理混合废物流和受污染的土壤，其中存在有机和无机废物。 路易斯安那州立大学和圣保罗的研究小组具有独特和互补的能力。 路易斯安那州立大学小组以固态核磁共振光谱学方面的经验而闻名，而圣保罗小组则在真实的废物流和有效固定含有机废物的混合物设计方面拥有广泛的经验。 拟议的研究将涉及在巴西进行的样品制备，以及在路易斯安那州立大学进行的光谱和其他性质的检查。 LSU集团将受益于巴西集团在粘土使用和改性方面的专业知识，而圣保罗集团将受益于获得用于固体表征的现代仪器。 ***

9415675 Cartledge This U.S.-Brazil Cooperative Science Program award supports travel expenses and expendable research supplies for work to be conducted by Prof. F. Cartledge and Dr. M. Titlebaum, both of Louisiana State University (LSU), Louisiana, with Dr. P. Buchler, Univ. of Sao Paulo, Brazil. Drs. Cartledge, Titlebaum and Buchler are conducting research on the solidification/stabilization of hazardous wastes using cementitious binders, a common technology applied to waste streams, mostly of heavy metal containing wastes. The use of organoclays as additives in the process has the potential for greatly expanding the utility of the method, particularly for the treatment of mixed waste streams and contaminated soils, where organic as well as inorganic wastes are present. The research groups at LSU and Sao Paulo have unique and complementary capabilities. The LSU group is noted for experience with solid state nuclear magnetic resonance spectroscopy, while the Sao Paulo group has broad experience with real waste streams and the design of mixes that are effective for the immobilization of organic containing wastes. The proposed research will involve sample preparation in Brazil, and the examination of spectroscopic and other properties at LSU. The LSU group will benefit from the Brazilian groups' expertise in clay uses and modifications, while the Sao Paulo group will benefit from access to modern instrumentation for solid characterization. ***
