✦ Synopsis
The nitrate conversion with liquefied NO 2 and the nitrate extraction with SC-CO 2 were demonstrated for copper powder and neodymium nitrate instead of actinide compounds. Copper contacted with NO 2 in an autoclave at 353 K changed to water-soluble compounds. By XRD analysis of the product in the atmospheric condition, the formation of copper nitrate hydrate (Cu(NO 3 ) 2 $2.5H 2 O) was confirmed. As for the extraction, neodymium nitrate loaded in an autoclave was successfully extracted with the fluid of TBP and SC-CO 2 at 15 MPa, 313 K.
