Abstract
In order to separate Rh and Pd from the reprocessing wastes of nuclear fuel, Rh and Pd are precipitated in metallic form through the formic acid denitfation process. In this process the acid concentration of the solution is reduced from 3.52 M HNO3 to pH~2,and Rh and Pd could be recovered from the precipitates way. The optimum technological conditions of formic acid denitration have been intensively studied here.
