Equipment is provided to develop research capability for two areas of study of the kinetics of fluid-solid interactions. One project is focused on the ionic mobilities and exchange properties of the family of beta-aluminas. Specific investigations have to do with proton conductivity for water electrolysis and with ion exchange for nuclear waste management. A second study examines the rates at which glasses are hydrated from vapor or aqueous solutions. The practical objectives of this study are also associated with disposal of hazardous material, since various glass forms have been proposed as containment matrices for high-level nuclear waste. These investigations both call for experimental determinations of ionic concentration and mobilities. The equipment consists of a frequency response analyzer, electro-chemical interface, impedence analyzer, and other components.

设备提供发展研究能力的两个领域的流体-固体相互作用的动力学研究。其中一个项目的重点是β -氧化铝家族的离子迁移率和交换性能。具体的研究涉及水电解的质子电导率和核废料处理的离子交换。第二项研究考察了玻璃从水蒸气或水溶液中水化的速率。这项研究的实际目标还与危险物质的处置有关，因为已提出各种玻璃形式作为高放核废料的容器基质。这些研究都需要离子浓度和迁移率的实验测定。该设备由频率响应分析仪、电化学接口、阻抗分析仪等组成。
