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

9415675 Cartledge这项美国-巴西合作科学计划奖为路易斯安那州路易斯安那州立大学的F.Cartledge教授和M.Titlebaum博士与大学P.Buchler博士进行的工作提供差旅费和消耗性研究用品。来自巴西圣保罗。Cartledge、Tilebaum和Buchler博士正在进行使用胶凝粘结剂固化/稳定危险废物的研究，这是一种应用于废流的常见技术，主要是含重金属的废物。在这一过程中使用有机粘土作为添加剂，有可能极大地扩大该方法的用途，特别是在处理混合废流和受污染的土壤时，其中既有有机废物，也有无机废物。路易斯安那州立大学和圣保罗分校的研究小组拥有独特和互补的能力。路易斯安那州立大学小组以固体核磁共振波谱学经验著称，而圣保罗小组在真实废物流和有效固定含有有机废物的混合物的设计方面拥有丰富的经验。拟议的研究将涉及巴西的样品制备，以及路易斯安那州立大学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. ***
