U.S.-Brazil Cooperative Research: Application of Solidification/ Stabilization to Tannery Wastes

9802427 CartledgeThis美国-巴西奖将支持弗兰克·K博士之间的研究合作。作者声明：Marty E. Tittlebaum，路易斯安那州立大学，和PersiodeSouza桑托斯，Antonio C。圣保罗大学的Vieira Coelho和Pedro Buchler以及里约热内卢联邦大学的Jo Dweck博士。 NSF的环境技术方案提供了部分支持，这项研究将着眼于有机和混合有机/无机废物的处理，特别是制革废物，以及有机粘土作为水泥基粘合剂系统的添加剂的使用。 将使用光谱技术比较不同的混合物，目的是确定有效处理的因素。圣保罗小组在真实的废物流和用于固定含有机废物的粘土材料的性质和用途方面具有广泛的经验。 LSU小组在采用各种方法进行机械研究方面具有专业知识，特别是固态核磁共振光谱学。 这些研究人员共同努力，可使我们更好地了解使危险废物有效固化/稳定化的过程。

9802427CartledgeThis U.S.-Brazil award will support a research collaboration between Drs. Frank K. Cartledge and Marty E. Tittlebaum, Louisiana State University, and Drs. Persio de Souza Santos, Antonio C. Vieira Coelho, and Pedro Buchler, University of Sao Paulo, and Dr. Jo Dweck, Universidade Federal do Rio de Janeiro. Partial support is being provided by NSF's Environmental Technology Program.This study will look at the treatment of organic and mixed organic/inorganic wastes, specifically tannery wastes, and the use of organoclay as an additive in cement-based binder systems. Different mixes will be compared using spectroscopic techniques with the goal of defining factors responsible for effective treatment.The Sao Paulo group has broad experience with real waste streams and the properties and uses of clay materials that are used for immobilization of organic-containing wastes. The LSU group has expertise in mechanistic studies employing various methods, particularly solid-state nuclear magnetic resonance spectroscopy. Together, these researchers could increase our understanding of the processes giving effective solidification/stabilization of hazardous wastes.***
