【 摘 要 】

The attached report is a summary of the work performed by Dr. Darsh Wasan, Dr. Alex Nikolov, and their researchers at the Illinois Institute of Technology (IIT) during FY01. IIT developed the IITB52 antifoam for SRTC in FY00 to minimize the foam produced during precipitation, washing and concentration of cesium and potassium tetraphenyl borate precipitate. The IITB52 antifoam has been very successful during continuous processing (prototypical of plant operation). However, there were several key issues where SRTC needed the experience and knowledge of IIT to resolve. As a result a subcontract was set up with Dr. Wasan and Dr. Alex Nikolov during FY01. This subcontract requested IIT to perform the basic research necessary to understand the foaming mechanism and explain the effectiveness of the IITB52 antifoam agent in the Small Tank Tetraphenylborate Process (STTP).
