Title: Heavy metal separations using strongly paramagnetic column packings in a nonhomogeneous magnetic field

Patent ·
OSTI ID:1650809

The present invention is directed to a method for the separation of an actinide from another metal. The method comprises the following steps: (a) establishing a non-homogeneous magnetic field across a separation column containing a paramagnetic packing material and (b) providing a fluid containing the actinide and the another metal to the separation column wherein the fluid and the paramagnetic packing material are exposed to the non-homogeneous magnetic field. The non-homogeneous magnetic field is produced by a magnet having a first pole for magnetic interaction with a second pole of the magnet wherein the first pole has a different surface area than the second pole. The non-homogeneous magnetic field has a magnetic field gradient of about 500 lines/cm2/cm or more. In addition, the present invention is also directed to a method for the separation of one heavy metal from another heavy metal.
