Abstract Scope |
Harsh environments represent a challenging but important area where advanced chemical characterization is needed. As an example, molten salts and corrosive gas streams play key roles in potential nuclear materials processing schemes. On-line monitoring offers a route to both improve fundamental understanding of chemical behavior and control process chemistry. This approach can provide the much-needed information regarding concentrations, oxidation states, and speciation of target analytes. Optical spectroscopy probes are also robust enough to withstand the harsh conditions. Here, applications of on-line monitoring to salt melts and off-gas streams will be discussed. These systems are currently being utilized to characterize fundamental behavior of lanthanides and actinides in chloride melts. Gas-phase systems are being designed to monitor for key analytes such as HF, iodine species and hydrogen isotopes. In all these applications, the use of chemometric analysis is being applied to allow for real-time identification and quantification of target analytes. |
