Latest Patents
One of her latest patents is titled "Process for trapping gaseous ruthenium on polyvinyl pyridine." This invention focuses on a method for recovering radioactive ruthenium from irradiated nuclear fuels. The process involves contacting a gas containing ruthenium in gaseous form with an adsorbent made from a vinyl pyridine polymer or copolymer, effectively fixing the ruthenium to the adsorbent. The gas can originate from vapors of fission products containing ruthenium, which are heated in the presence of an oxidizing agent to volatilize the ruthenium.
Another notable patent is "Process for the separation of certain elements from aqueous solutions." This invention addresses the separation of elements such as niobium, antimony, cerium, and actinides from aqueous solutions resulting from the reprocessing of spent nuclear fuels. The method involves using a solid resin based on a vinyl pyridine polymer or copolymer to fix the desired elements, which can then be separated from the solution.
