The effect of nitrate on Th extraction by primary amines was studied. Selectivity of the primary amines can be greatly improved by adding alcohol to the kerosene diluent. The flow capacity of settlers for NaCl stripping in the Amex Process was determined in a 6-in. settler for alcohol-modified and unmodified 0.1 M Rohm and Haas LA-1 amine m kerosene A process scheme is proposed for the recovery of U and Pu from H/sub 2/SO/sub 4/ stainless steel decladding solutions, by extracting U/sup 4+/ and Pu/sup 3+/ or Pu/sup 4+/ with successive streams of 0.1 to 0.3 M primary amine and stripping ihe combined extracts with dilute HNO/sub 3/. The structural effects on Th and U extraction with neutral organophosphorus reagents were studied. A flowsheet was developed for the extraction between TBP and HNO/sub 3/. The kinetic behavior of amine extractants was studied. (W.L.H.)
