<p><P>PROBLEM TO BE SOLVED: To provide a method for recovering platinum group elements by which the fractionating of platinum group elements by remote control corresponding to a high radiation field from a high level radioactive waste liquid is possible, while the use of a separation agent to form into secondary radioactive waste is suppressed as possible, and platinum group elements can be recovered as metals for reutilization, and further, fractionating with high selectivity and a high recovery rate can be achieved. <P>SOLUTION: A platinum group element ion-containing solution is irradiated with an ultraviolet region wavelength leaser to reduce the platinum group element ions, and the produced platinum group elements are recovered. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
