Abstract
A new chemical method based in two separation steps was developed to i solate Np-235 from uranium targets irradiated with charged particles. Neptunium and plutonium are separated from uranium and most of the fis sion products by ion exchange. Then, neptunium is isolated from pluton ium and remaining contaminants by extraction chromatography with tribu tyl phosphate in hydrochloric acid solution. High decontamination was achieved.
