CHEM 418 Nuclear Chemistry, Winter 2016: Lecture 17 Separations
A number of different separation methods for radionuclides, with an emphasis on actinides, are presented. Solvent extraction, ion exchange, electrochemical, volatility and ionic liquid methods are discussed. The fundamental concepts are provided with specific examples on the nuclear fuel cycle. Ideas and concepts for advanced separations are given. Details are provided for the different separation routes discussed. The PUREX process is described. Examples are given for TRUEX and TALSPEAK separations. Specific examples for actinide separations are provided. Part 4 is a summation lecture on transuranic separations that are drawn from the Np, Pu, Am, and Cm lectures. Part 4 is meant as a review and provides a compilation of separation methods, the bulk can be skipped, but examples of questions are provided at the end of the lecture.

I'm getting a bit confused about ion exchange elution order and question 3. If an element has a higher distribution coefficient at a concentration of HNO3, does that mean it is more retained on the resin, and therefore eluted last?
ReplyDeletethe distribution coefficient is the concentration on the resin over the concentration in the solution. If the value is high then the concentration on the resin is high. Your reasoning is correct.

ReplyDeleteI received your quiz, thanks!
DeleteI have emailed you PDF quiz 17.
ReplyDeleteI sent the lecture 17 pdf quiz as an attachment through email.
ReplyDeletethanks for the PDF quiz for lecture 17.
DeleteLecture 17 sent via Canvas. I liked it, it was very similar to many things we learned in biochemistry for protein and nucleic acid extractions.
ReplyDeleteGreat to hear the overlap!
DeleteSent me quiz as an email.
ReplyDeleteIt's interesting to be back in familiar territory. But performing extractions with radioactivity elements does seems more intense than the extractions we did in OChem.

same ideas. Maybe just less material.

thanks for the PDF quiz.
DeleteLecture 17 part 1 viewed and quiz sent. I would have watched the other parts, but I couldn't get them to work...
ReplyDeletesorry about that. I will check on the other parts.
